Here's my rig hooked up to my 2008 20' Logan Coach horse trailer. A 2001 GMC 2500 3/4 ton Short Bed with 8.1 Liter Big Block V8 with Allison Transmission. Bought it in June of 2007 used. It Drinks the Gas but boy can it pull. It also pulls my 2007 20' Titan Gooseneck flatbed. Loaded with my John Deere Tractor & Gator or loaded with horses it pulls em' very well. Pulls as good as a Diesel. GM discontinued the 8.1 Liter V8 in 2007.
I just replaced both Catalytic Converters on it with Magnaflows and a fresh oil change , new air filter, radiator flush with new coolant , serviced transmission , new fuel filter and replaced the shift lever. Will be putting new plugs & plug wires on soon. At 142,000 miles it still runs great. Best truck I have ever had so far. If I replace this truck, I will probably get another one with the same engine and tranny. I love GMC Trucks. :thumbsup:
