Wothahellizat Mk2 DIY Expedition Motorhome

This is the story of how two people, at the age of 45, quit their 9-5 jobs, sold just about everything, and built this awesome Wothahellizat Mk2 DIY expedition motorhome to travel and live in.

The back story is basically that at the age of 45 we had both had a gut full of the 9-5 treadmill so we quit our jobs, sold just about everything, built Mk1 of the truck (the one we are talking about now is a rebuild that I call Mk2) and hit the road.

That was back in 2001. We have now dropped anchor for a while and have almost finished building a house from shipping containers.

    I love tiny homes, I build super fancy ones myself, but after seeing this one, I must admit, it is so inspiring to me because… it is very plain on the outside but he made the interior super cool looking and functional as well,…It is really a hip and very cool tiny home-!! and it can go anywhere.. ROCK ON-!!!!!!!!
    This is truly a work of ART Thanks for sharing..MO

  • Rick Pain October 29, 2015, 8:13 pm

    Fan-tas-tic ! A *****A
    This is exactly what I require to tackle Australia.
    I have a budget so I’m in need of your assistance please.
    I have briefly overviewed this article and I’m anxiously curious about the Truck & the running costs as well as the overall cost.
    Sincerely,
    Regards,
    Rick.

    • Helena October 30, 2015, 2:05 am

      Me too.

    • Rob November 2, 2015, 8:10 am

      Cost is hard to say, I estimate about $90k for the truck, new motor, materials etc etc.

      Fuel consumption is 4k per litre, which is not bad for 12 tonnes, many Landcruisers with caravans get similar.

  • Kristina H Nadreau October 29, 2015, 8:18 pm

    This work is so awesome that words fail me. The organization is genius, craftsmanship is extraordinary, function is beyond dreams…

    Congratulations Rob Gray. No one could have done it as well. Alex, thank you for giving us the opportunity to see this wondrous creation. I am blown away.

  • jerryd October 29, 2015, 8:24 pm

    Very nice cabin, terrible choice for the truck getting 5-6mpg and no need for such weight.
    A 2 ton 4wd would have went anywhere too.

    • Rob November 2, 2015, 8:20 am

      What can I say, I just love these old ACCOs.

      It gets nearly 10mpg which is not that bad, better in fact than some 4x4s with caravans.

      A FWD at 2t does not have enough capacity for long periods in the outback, I’ve done heaps of that type of travel and I’ve never seen one under about 3.5t when properly fitted out with tools, water etc etc. And even then you can only stay out for a week or two without resupply of water at least.

      In this truck we can literally sit in the bush for 3 months (in theory), certainly we’ve done 2 months many times without seeing a town and hardly another person.

      Anyway this is NOT a vehicle to go anywhere, that’s what our 4×4 is for. This is a vehicle to live in for 15 years (as we have done) and as such it needs to be a reasonable size. You can have comfort or you can have serious off-road ability, you can’t have both.

    Very impressive, very inventive! Kudos on the ultimate moveable man cave! I’d bet Hollywood would love to rent it for an apocolypse movie! Fun and brillant execution!

    • Gord. October 30, 2015, 9:51 pm

      I was thinking to myself that it looks like from apocalypse movie like the new mad max ;)

  • Anna Granfors October 29, 2015, 10:35 pm

    …wow–just…WOW…

    It just seems hard to reconcile the co-existence of Tumbleweed-type tiny homes and (as Brian Lund said above) zombie apocalypse vehicles like this on the same webpage. Don’t know if anyone remembers the old print magazine for proto-survivalists “Soldier Of Fortune”, but this would fit comfortably there.

    I sometimes despair that my sanity is irrevocably gone. This is one of those times.

  • Mike October 29, 2015, 11:43 pm

    These are great units!! I’m not a prepper, but there is no doubt to the high level of quality and inventiveness going on here. And to top it all off I really like the drop down armored awnings. Not only do I simply like awnings, but believe they should be functional for extreme weather. If s*** ever does hit the fan, I’d probably wish I had one of these!

    • Kimmie October 31, 2015, 6:02 am

      I hit that report comment button on accident! So sorry

  • Helena October 30, 2015, 2:04 am

    Brilliant idea, especially for Australia which is NOT tiny house friendly like in the US. Also our roads are far worse too. Canadians would understand. In Australia, councils and governments do not like the concept of tiny houses as, if you are independent, they cannot finance $15K taxi rides for themselves. (Really!) Councils will try and throw every single regulation at you that they can. The fines are exorbitant. A tiny house truck solves this problem entirely. As long as you lie and say it is for RV purposes, you can have financial freedom.

    • Rob November 2, 2015, 8:24 am

      Yep, we’ve been living in this all over Oz for nearly 15 years, and in all that time have barely paid a cent for accommodation. A few $ in the occasional National Park and that’s it.

      We now own land and are living in the truck on that, our council is pretty good actually but if we do get pinged we simply pack up, bugga off and come back next week :)

  • Glema October 30, 2015, 4:08 am

    i love it! I too have a hard time convincing hubby Dana. I did finally get him to offer a fifth wheel first to try things out. He wants a “home port”
    as well. He isn’t ready to let go of all the stuff we have. Personally, I’ve already started to get rid of things. We did downsize to a 1100 sq ft apartment from a 1900 square foot house. So baby steps. But one day…
    Thanks for sharing Rob. Nice job!
    I’ll show him this and see what he thinks. Maybe just need to appeal to his macho to get my tiny hehehe. God bless and happy trails!

  • rick October 30, 2015, 6:24 am

    o.k. how much sweet heart !!!

  • Chel October 30, 2015, 6:47 am

    The name alone says it all. Then I saw the first picture and knew it couldn’t be called anything else. Brilliant.
    If 5 or 6 mpg is right, the base isn’t one I would go with.
    Great ideas and inspiration though.
    Great layout and planning – the result of living in it makes a huge difference. Some of the cute wood finish THOWs are obviously made for the market by people who would never dream of actually living in one themselves.
    Those awnings for both shade and security can’t be bettered.
    It would look like an ordinary wagon in an urban lorry park.

    • Rob November 2, 2015, 8:30 am

      Standard these have a petrol motors and the 5mpg is probably about right. But we put a diesel in and get about 10mpg.

      Security is top notch, the lounge room is 2 metres in the air and the bedroom 3m, so even with the windows open it’s not easy to get in. We always close the lounge shutters at night but are quite happy to sleep with the bedroom shutters open, great in the hot weather.

      Apart form that I can easily get onto the roof from inside and pour boiling oil over any invaders.

  • Pamela Woods October 30, 2015, 4:18 pm

    I would love the follow ups to this. I agree, break down of costs and hints, please, bring it. I’ll trade you a week at my vacation home in Tucson for the directions. Cheers to you, this rocks.

    • Rob November 2, 2015, 8:34 am

      I posted total cost above, but as a rough guide

      Truck, $30k with recon gearbox, recon Perkins diesel, and stretched chassis.
      Mk2 body, $45k
      Solar and all appliances, maybe $15k.
      My time (3 years for Mk1, 18 months for Mk2), priceless.

      I’ve been to the US and loved it, but doubt I’ll ever go back, you can stay here in it for a week though if you like :)

  • Porcsha S. October 31, 2015, 9:15 pm

    Close to being amphibious! Cool house!

  • Pete November 1, 2015, 2:36 am

    For those asking, I’m fairly sure the build cost was somewhere in the ballpark of $150-200k. At one point the Mk1 was up for sale for around $120k (from memory). He had the chassis extended on the Mk1 and shortened again (though longer than standard F1) on the Mk2.
    MPG/ L/100km is around 5-6mpg on these trucks, and though he runs a Perkins diesel it was still an older motor and I’d imagine it would get similar mileage. The best thing to do would be to swap in a newer of more efficient diesel motor and gearbox. Standard these trucks don’t like going over 80km/h on the highway and chew diffs, but when you’re driving such a beast I doubt you’d need to go much faster very often.

    • Rob November 2, 2015, 8:41 am

      Pretty right there Pete.

      I have just covered costs and mileage for Mk2 above.

      We never really kept records when building Mk1 but I estimate about $180k.

      80kph is tops, especially with the lower revs of the diesel as compared to the original petrol motor. Any faster and it’s just too hard to drive, in fact I’m happy to potter along at about 70kph. I’m in no hurry (last I kept records we averaged 137k per week) and in the outback the roads are long and straight so people can pass easily.

  • Pete November 1, 2015, 2:41 am

    My apologies, my post above mentioning price range was mistaken. I re-found an article quoting Rob would sell the vehicle (at the time) for $250,000 USD.

    • Rob November 2, 2015, 8:46 am

      I think at the time I didn’t really want to sell it so put that price on in case an oil magnate decided he wanted a new toy :)

      As with all things they are worth what someone will pay, my time and the cost of materials don’t really matter. I did have someone email me a few weeks ago and ask for a price, I haven’t heard from him since. I guess he thought he’d get it for $20k or something.

      We have a house so don’t really need the truck now, but I’ll keep it as a bug out vehicle before I give it away.

  • Thom Brand January 26, 2016, 4:05 pm

    This is it,this is the one!
    You’ve pegged it!

  • Thom Brand January 26, 2016, 4:10 pm

    Above.

  • Elizabeth February 11, 2016, 7:53 am

    Very Impressive!!! You have inspired my husband and I to build one along these lines. I love the truck choice! Could you perhaps post a pic of the bathroom please? Thank you!

    • Rob Gray February 11, 2016, 6:19 pm

      Actually Elizabeth there isn’t a “bathroom” in the normal sense of the word. The entrance is used as a shower, toilet, laundry and home brew work area depending on what is slid out.

      That said I should have some photos of this lot but don’t appear to have any.
