I have the 2015 Tacoma Prerunner SR5 w/tow package, I guess the equivalent truck and I pull a Rockwood 2502 mini lite. It is 4300lbs dry probably 5500lbs loaded without water, and empty waste tanks. I have to say the Tacoma as it comes with a tow package isn't ready to tow a TT. Certainly not powerful enough to pull on cruise control leaving the computer to decide gas and shifting. I had to modify my factory truck to make it safer to tow with; for instance I replaced the factory tires with Light Truck tires rated load range C. They have stiffer side walls makes for kess drifting from vehicles passing and wind gusts. I already had a 7 pin connector but I purchased a weight distribution hitch with thick 12,000 lb rated friction trunnions to reduce sway. I also had a proportional brake controller installed to help keep that trailer back their where it belongs. Probably $1000 bucks in tires and equipment in addition to what the factory tow package provided. I also do not use cruise control and in fact do not even use overdrive. The computer is a terrible judge of when to shift and how much throttle it needs. 4th gear at about 2200 to 2700 rpms gets me 60 mph to 65 mph on the highway. Definitely not higher than 3200 rpms on steep hills. No issues pulling with this strategy. My gas milage is usually 10 to 12 miles per gallon. Sometimes when there's a long steep down hill, I'll use the overdrive gear to save gas but it's the exception not the rule. You have to drive the truck definitely not able to just ride along like normal. Towing takes constant attention to your environment, and your rig.
