Apologies for not seeing this message until a year later! I have been towing our Geo Pro 19BH for two seasons now and have had no problems in the mountains. I just take it easy on steep passes, but even still has been great. I highliy recommend getting a weight distribution hitch. This one: Fastway e2 Weight Distribution w/ 2-Point Sway Control - Trunnion - 6,000 lbs GTW, 600 lbs TW
