Here is our Tahoe pulling the Churches 20' 10k GVW Interstate enclosed trailer. Loaded it weighs 6400lbs w/ @650lbs of tounge weight. Here is my 4cyl S-10 work truck with a 9' U-haul I rented to pickup some appliances. This truck doesnt like trailers too much. Not enough power for hills:doah: .
Here's a pic of when I rented a 10K giant vaccuum rig. It's got a Deutz diesel and man that thing was silly loud with the vaccuum going! We spilled rice into a silo that contained corn, we sucked out 75,000lbs of rice off the top of the corn with that thing.... Here is just the other day, I had to move one of my disks (Case 770 21ft) out to one of my ranches to where the tractor was at, this sucker is heavy.
Here's our Motocross Rig, which consists of my 2006 GMC 3500 DRW w/LBZ & Allison Tranny. The trailer measures 22' from nose to tail and is 7' wide. When loaded-out with 6 bikes and gear it weighs approx. 6000 lb. which comes nowhere near the trucks max. capacity but man it sure is comforting having those two extra tires when towing.
