2001 monaco knight 36r with 260 cummins

We tow a Jeep Wrangler Saraha 4 door with a 32' 2002 Horizon with Cummins 5.9 liter 300 HP ISB. And the Allison 6 speed. It tows fine up the hills if you get a reasonably good start. Not good starting out from a stop at the bottom until you get going. It's a bit low on torque but has serve us for 5 years (2 with the Jeep, 3 with a Chevy Tracker) I agree with others, find a rig with the Allison 6 speed.
