I have used the 275 to tow my 37 ft 5th wheel toy hauler alot, like 5000 miles or so. It weighs about 12k. The only problem with the 275 is if u have the cruise set and go into a hill, when it downshifts the boost can get scary high if the hill is steep....i think 57psi is the max the gauge will read or something close to that, i was scared i would blow a boot off, so i usaully use the tow tune now, the boost doesnt go as high.....that's with the old tunes, havent loaded the new ones from earlier this month yet(April 2011)!
But other than that the old 275 worked good, apart from a bit of bucking/surging onces in awhile, even with the cruise on.
Mileage is way better with the 275 though.
