A pickup to tow a 10K lb TT or 5er
The 1st I'm considering, is a new 2500 Reg Cab, Long Box WT RWD, 6.0L V8 (360 hp & 380 ft-lb torque) Curb Weight 5817 lbs, Max Payload 3534 lbs, Max GVWR 9.3K lbs. W/Conventional tow rating of 14.5k lb w/4.10 rear gears.
The other is a Toyota Tundra, 2WD Reg Cab, Long Box, w/5.7L V8 (381 hp & 401 ft-lb torque). Curb Weight 4940 lb, Max Payload 2060 lb, GVWR lb 7K &
Max tow cap is 10.5K lb (w/4.3 rear gears & towing package).
10K is the GVWR of the RV. It should way more like 8.5K loaded. I'm wondering why with more torque & a higher axle ratio, the Tundra is rated so low on towing. Anyone have any ideas why this would be the case. I'm staying away from turbocharged gas engines. I don't believe they are worth the loss of dependability they cause. The Tundra has an all aluminum block, I doubt it last as long as an iron block.
Any idea which of these two work work better and be the better buy?
