Just signed up on this forum after lurking a while and wanted to say hi and looks like a good forum. I do not yet have a Tacoma, but seriously considering one. My question concerns towing, first the details. I live in Phoenix and tow an Aliner Expedition which is 18' and weighs 2078 pounds (per CAT scale) empty except with 2-full tanks of propane and a couple gallons of water on board. The gross vehicle weight of the trailer is 3500 lbs. but it never sees more than 2500 lbs loaded for a camping trip. I have no question a Tacoma can tow my trailer as it falls well within the tow capacity of a Tacoma with tow package, but want to know if I can expect to tow it up mountain grades in the 5-7% range in 100 plus temps with the AC on? I am asking because I currently have a 98 Jeep Cherokee (also a 6-cyl & with a 5K tow capacity) it has the giddy-up to tow it up steep grades, but unless I turn off the AC and keep the speed to 45mph, it tends to overheat. Considering the cost, I want to make sure before buying. Thanks, for considering my question.
