Considering Heartland North Trail 24BHS

Sounds like a pretty good package and I've heard a lot of good things about the Azdel, but no experience with it. There is always a debate of fiberglass sides vs. aluminum, just a matter of preference. The smooth sides look nice, easier to clean and less likely to be hail damaged, but I have seen some that delaminate which becomes an issue.

I doubt you're going to find many shorter TTs with bunks.
