I have a 3/4 ton burb with a performance chip (not sure the chip helps) It tows like a champ on flat roads, but mountains and steep grades I always have problems with the tranny overheating. I have started towing over potasi in a lower gear and that helps a little. But sucks having to go 30 over the mtn. Stopping has never been an issue. Coming down potisi has been a little hairy at times, but I tend to use the trailer breaks more on that and also use a lower gear.
My hauler is a 21 ft rampage, and typically I only have 1 bike in there. Hope this gives ya some help!!
