If I was to order one it would certainly be the HD Max Tow. I feel fortunate to find the Max Tow I did on a lot. I have not seen any HD models either on the lot or on the road. They seem to be a rare bird around here.
You will be limited if you decide to go to a FW without the HD payload. We were even with 2080lbs. Our previous TT was a 35' Keystone and sway was a consent battle. The FW tows like a dream but I have to be careful not to exceed payload. Full waste tanks kick me over.
I can't say enough about the drivetrain. Tons of low end power.
