Why would someone choose a Park Model sized Tiny House on Wheels? At almost 10’ wide, our Big Little Barn is surprisingly roomy inside. Like roomy as in, you don’t have to limit your guest list to one person roomy. As in, you can have the whole family over and not be tripping over Uncle Walter’s dog roomy. So for those who want more space and don’t plan to use their tiny house as a travel trailer, the Big Little is an excellent choice!
