Trailers with compressor fridges with inadequate battery power to run them. The one 5.0 had a composting toilet mounted. Because it sits up on the black water tank you would need a step stool in order to just get up on it to do your business. Otherwise you would have to literally jump on and off. Silly. And to me if you are foaming a trailer why wouldn’t you put tank heaters on first? They are super cheap even if you don’t plan to use your trailer in cold weather. But a big negative if you want them installed after the fact or look at resale. And a number of trailers with older style sliding glass windows. Trust me when you see the ones with acrylic you’re going to want it. Way nicer blind/screens, open all the way, stay dry, and they are much larger to let in more natural light and air. I won’t even go into how thermally superior they are to glass. They make the trailer I tell you.
. We didn’t go with the foam but plan to add our own, and after 4 years in our T@B the acrylic fully opening windows were an absolute requirement, for all the reasons you cited.
