I certainly don't think 32' is too long. Ours is a little under 35' and we have had no problems. I favor state parks. Ours is 13'3" high, 10,600 unloaded, and loaded weighs a little over 12K. I pull it with a 2016 Ram 2500 with the 6.4 Hemi and 4.10 rear axle ratio. Pulls great. Tow rating is about 16K, but I wouldn't like to pull more than about 13-14K with it. Does it pull like my previous diesel - NO- but it pulls well. Towing the fiver I got about 11 mpg at 65 mph with the Cummins diesel and I get 8 mpg with the 6.4 hemi. I could pull anywhere in TN and KY at 65. Yes, in Colorado it may take me a few more minutes to climb the mountain pass than the diesel, but I can live with that. I think the 2500/250 gassers from any of the big 3 with the right rear end would work well. I think 32' is a great size, but DW wanted bigger so we compromised at 35'. Good luck.
