The trailer we are looking at weighs #5595 according to Grand Design, with a hitch weight of #505. We will get a new tow vehicle to handle this weight, I am considering 1500 Eco Diesel, 1500 Hemi ...
For me, a big consideration would be the 8 spd transmission in the 1500 vs the 6 spd in the 2500. If the weights worked and I had no intention of getting a heavier trailer in future, I would be looking at the 1500.
