@Cinnamongrammy maybe a medium house? Or cut more? I went other way more space and storage for my stuff. Moved from city to country to allow for this along with start living what I feel is right, not in a cage I put myself into.
The mobile tiny houses can be upgraded with larger heavier axles platforms. Depending on what you have to tow it with is the limit. We made first one on a 7500 lb total weight trailer, huge learning curve. We are now looking at using a old heavy equipment trailer. Got it for 2000, the deck is a mess and needs to be replaced the brakes and tail lights redone.
The other option we have done is a container 20 foot, finding a used one with a refrigeration unit, you can find one for under $4000. Using this set up you can get a tow truck to move you if you don’t own one for longer trips it fits on intermodal transport, this means train trucks and sea cargo ships. For ideas how build look at ship builders techniques for sto rage and maximizing space.
It’s just one of many ideas for a home that is mobile and non traditional. Remember you can pack it full for transport, unfold it and take stuff out when you arrive.
