We have a travel trailer. Here is the one we have though we bought it in 2016

We have a unique set of circumstances that make it a good fit for our family. However, no way would I want to live in it full time. It can be cost effective if you use it enough. But, it is less of a vacation and more of a trip. We’re headed to the beach in ours next week and am already washing bedding and making lists for the food.
