We have the same truck as you only in a crew cab. We are pulling a Keystone Laredo 240MK with a loaded weight of 6300 lbs. Trailer is 27'-8" long and almost 11' tall. The truck handles it well and pulls fine even on steeper grades as long as you are willing to push the rpm's. The 6 spd. trans does make a big difference vs. the old 4 spd. We just towed through some pretty steep grades in NY and PA. On our way to Virginia this week and I was quite pleased with the stability and performance. Just be careful of your payload and do not overload the truck.
