[QUOTE="sexxy, post: 460352, member: 6598"] 2000 gmc crew cab k2500, 5.7 ,4l80e, 4.10 gears 285/75-r16. I tow a 8x24 bumper pull homemade trailer ~2000lb, rhino, and tj so total should be around 7500-8500 trailer weight. I usually get 10-12mpg with only truck unloaded. With my for mentioned trailer weight and spare parts it gets 8mpg running 55-70. Once had near 13k gooseneck trailer weight and got 7.4mpg running as hard as I felt the engine could stand. Running 65mph in drive the 5.7l is turning 2400-2500rpm when the torque converter unlocks it gets ~3000rpm and sounds like it's revving hard but not making any more power. Best I ever got was 15mpg traveling up natchez trace from Jackson ms to tupelo ms running 55mph max. What's your rig get? [/QUOTE]
