Looking at TT and 5er...looking for input on that and brand

From where you are, I'd look at Nordwoods MFG. Snow River 288 looks like a good fit for your family.

Agree! I certainly would look at Northwood products. Arctic Fox is their top of the line and has their own frame and is what they call a four season coach. From what I can tell they are well built. A little heavier then other trailers, but your diesel will tow one with no issues. I think they make a 31 foot bunkhouse. It is an impressive trailer.
