I keep on learning so much from everyone's posts as well as replies. What a great bunch!
I appreciate this so much, as it helps me figure things out whilst on this crazy quest.
OK, so there ARE things I can do regarding after-market changes. In a few other posts, some owners had suggested such changes would be cost-prohibitive, or not possible. But now, I am aware of not only a product that would help to add insulation, but also a method in which to do so.
There were also other ideas I found when searching for winter camping, or plummeting temperatures...very helpful!
I was just leery of the effectiveness of doing these things, especially because of my unique requirements (health issues). Also, to do these and other changes to adapt the trailer to my needs may prove to be physically difficult for me. But I can figure out other ways to do this, of course.
Ok...again, a big thank-you to all who have posted and contacted me.
Please keep your eyes and ears open for any trailers that pop up for sale...send along a PM!
