Hi Neil. I tow a 3500lb Airstream Bambi with my 2017 Ridgeline AWD and have had no problems in the mountains of Colorado and California and the deserts of AZ and Utah. In fact we’re on a 3000+ Mile four week trip right now and have had no issues. I carry two conventional bicycles and one e-bike plus all our gear. I have had the transmission overheat once last May and that has been the extent of my issues. I bought it with 35000 miles on it and have 59000 miles on it now. I plan on changing the transmission lube twice as often as called for and I have oil changes every 3000-4000 miles. I’d send you a picture of my rig, but I’m not sure how to do it on this website. JohnThe Ridgeline's towing capacity is 3500pds in 2WD and 5000pds in 4WD. I want to tow a camper that weighs more that 3500pds, how do I put the truck into full time AWD? Or does the truck figure out that it's pulling more than the 2WD capacity and make the change to ADW automatically?
