At first I wanted a bumper pull TH around 27', but then I seen a 5th wheel @31' and after a little research I've concluded it's a pretty decent built TH. Attitude 28SAG. I'm hoping my Truck isn't to...
I think I would be scared to tow a raised fiver with your truck. The 37's don't have the stiff sidewall needed for stability, they are off road tires. If you do it, take it slow on a side road to get the feel before venturing on the highway.
