RGSMDNR, I recently bought a 36' travel trailer. When it's loaded with everything we just HAVE to have for camping,
, I'm sure the weight is around 8000 lbs. We just came back from a trip to the Texas Hill Country, and I am SO impressed with the pulling power of my 2008 F150. I was able to maintaing 55-65mph very easily. Now, when I hit a long, gradual uphill grade .... I'd have to mash the pedal, the rpm's would jump up to 4000-4200, but I never felt like the truck COULDN'T handle the weight.
I know that my TFT has been around the 230 degree mark area a couple of times, so I'm going to flush the fluid and go with full synthetic. But even with the TFT up quite a bit more than yours is indicating, I still had plenty of pulling power.
Just my
