Back in 2000 I had a 2001 FB3000 Weekend Warrior custom built for me with all kinds of extra bells and whistles (Huge generator, 2 fuel stations, 3000 watt exterior sound system, 3000 watt interior sound system, 50 amp service, extra air conditioning, etc.etc...) which equalled a whole bunch of extra weight! I was able to carry (1) 5 seat Tatum car and (1) extended length banshee. I towed it with a 2001 Chevy HD crewcab short box 8.1 ltr V8 Allison 5 speed auto tranny, the truck had a twelve inch lift and 39" Mickey Thompson tires with 4:56 gearing. I towed all over the place, I never got stuck and it towed just fine! (Although it was not the quickest setup over the hills) I hope this information helps in your quest for a lifted tow rig and trailer!
