Cabin-Style Ram Promaster: Copper Shower, Rooftop Deck, and Queen Bed

Karol and Austin are the bubbly and awesome couple who built this beautiful Ram Promaster. On the cusp of buying a home, they chose to jump into van life instead—and created one of the coziest cabin-like conversions we’ve seen.

Karol had wanted a closet and bathroom, and they managed to fit both beautifully. They have a nice projector setup for watching TV and a lovely kitchen with butcher block countertops and a deep sink. The warm wood interior gives the van a true cabin feel that’s hard to find in most conversions.

    The tiny house movement has been co opted by elitists and classism.

        Nope, something like this just isn’t going to be at a price that everyone can afford. Point of fact is Van Conversions/Class B’s are normally more expensive than most other RV’s. Custom, especially, typically start over $300K and actual elites may pay up to multiple times that as well.

        The reality is to actually get really low prices requires effort, finding alternative and creative ways to get it done, and carefully making choices to get the desired result. The movement is about finding alternatives and being creative but that was never going to result in a magic solution that makes the consequences of choices no longer matter to costs.

        DIY and working on fixer uppers are typically where you find actual low prices, for example. However, people aren’t going to work like slaves and there are very real reasons for costs. So those low prices aren’t going to easily transfer to anyone else unless they are willing to do the same.

        There’s multiple ways to do anything but each way has its own costs and thus what’s realistic to expect by a given method will be different. There are always trade offs and consequences for every choice. It helps no one to ignore this and pretend there are no reasons for these differences…
