TT: What are the differences?

Potentially looking at 22'ish NT, Sundance, Wilderness, Mallard, etc., non stick & tin models. Did see the NT, Mallard, Wilderness appear to have WideTrax, but not the Sundance. (Another void here coming from pop-upers). Any thoughts going the car comparison route, i.e. Chevy, Pontiac, Buick, Olds, Caddy? Thanks.

Welcome to the forum! My advice would be to go with the floor plan that works best for you and your family. Just take a day and go look at several models, when you decide on one make sure you do a thorough pre-delivery inspection (oregon_camper is a member here and has a great one) before you sign. I would also try to avoid Camping World. There are several horror stories on this forum (and others) about dealing with them. Let us know when you find one. Happy hunting!

Mallard is basically a North Trail that is private labeled for Camping World.

I don't know much about Wilderness but my sense is that it's a lower price point product.

I have a Sundance XLT. It's an ultra-light unit with hard side walls.
