Glad I found this link. I have an 05 V6 4x4, and pull a Dutchman 1204 12' pop-up. I have a 3 inch lift, and 32" tires on stock wheels. I have installed a cold-air kit, and a TRD cat-back exhaust. I live in Arizona, and I have to travel up the mountains most every time I want to camp. With everything loaded, my truck struggles pretty much all the time. From the time I drop it on the hitch, OD is off, or its 60mph on the flat highways. With OD off, it tows ok, but as soon as I point it up a hill, it's workin really hard. I can't just sell it and get a V8, nor can I afford a supercharger. 99% of the time, its the wifes familymobile. On camping weekends it the TV. I'm trying to see what options are out there to help this thing up the hills. Any medium hill, I'm at 3500 rpm, buzzin in 3rd with the AC off. Any STEEP hill, I'm in 2nd gear. Is this what all of you guys are doing too? Going up the hills stresses me out cuz I feel like Im wringin its neck to maintain any speed. Now, Im climbing from 1500 to 7-8000 feet, so it's pretty steep. I was thinking a gear change may help offset the tire size change, and help with the hills. Anyone have any mods that work for them? Performance chip... gear change... turbo? lol
