Recognize your CC38efk is really 41ft long. We stay at a lot of state parks and some national ones. Our last 5er was 34’, and current one is 35ft...that was max length I wanted to go. Our length limits us somewhat, but not significantly. I do carry a pole saw because height can also be an issue. We haven’t traveled much in the NE where I suspect we’d be limited a little more but still doable. 41ft would be well beyond a lot of sites, but if you’re willing to stay at commercial parks I’m sure you can still always find something. If you wand state and national parks I’d look real hard at your need for >40ft.
Regarding trucks, I assume you have a diesel dually 1T for the trailers you’re looking at.
