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 ...
Ram 2500 offers (higher rated) coil springs like the Ram 1500. With Ram half tons currently at 400-600 pounds less payload than similarly equipped GM/Ford, I would go for their 6.4L 3/4 ton.
