Here is my old Tow set up.
In the beginning there was my Crew cab GMC 750 4x4 four door with Detroit Deisel. Camper slid into the back. It was cool, but extremely underpowered and slow!!
Next Came my custom three door Dodge 350, 12valve cummins.
Then came the Tow Rex 6x6. This one I regret selling. It was six wheel drive, with custom cab, camper went into the back, it towed great, but I wanted to upgrade to the newer Dodge. I should of kept it...:-\
This is what replaced the Tow-Rex
This pulled very well, but after a trip to california we stopped at a scale and we weighed in at 27, 880 lbs. The truck had no problem pulling it, but my insurance company said that if I were to get in an accident, even if I was not at fault, no insureance would cover me.
So for all of you who are pulling more than your truck is rated, you may want to be careful. You may find yourself not covered and out $Millions!!!!! So we bought a truck that was rated for that kinda weight.
So along came the GMC 5500 4x4
It works pretty good, Duramax, 4x4 allison....etc....The Dodge could still out pull and out stop this rig, and out MPG this rig, but hey....Im covered!!
