Tow vehicle

BGTV8

+1 for F250 Super Duty .... on the basis that all good things in motorsport go better with "lots" of everything (horsepower, brakes, etc).

In OZ, we get the Nissan Navara STX 550 ..... is a 4-door "ute" (short for utility - front seats like a car, but load area out back) SUV with 3500kg rated tow capacity, but not sure if they are available in USA. Is fitted with Renault-sourced V6 TT diesel that makes 180Kw and 550Nm of torque.

I personally tow with a Ford XR8 ute - Oz-designed "ute" (there is that word again) which has 5.4 litre Ford V8 from the F-series, but fitted with Cobra 32-valve heads (special manufacture for Oz), which I run on LPG (propane to you guys). It has a 140 litre propane tank in the tub out back and gives 650Km range on LPG and another 450 on regular fuel. On propane it makes 290Kw but more importantly, 525Nm of torque.

Trailer is an open-deck job weighing 650kg (we also carry 6 spares race wheels, two boxes of spares plus two tool boxes and 4 x 20-litre fuel cans, which weighs ~ 250kg all up) and the race car weighs 970kg. I tow this rig ~6-8000kms every year for the series I compete in, and have done so for the past 20 years - my tow vehicle's last around 5-6 years before the transmission gets tired (I also have an extra large transmision cooler fitted to reduce the AT fluid temps for this reason).

If you can afford a dedicated tow vehicle, get one ... IMHO they don't depreciate that much if you buy one which is ~3 years old, and the heavier carry/tow capacity - the better. Diesel makes for lots of torque which makes for an easy tow .... torque is your friend in a tow vehicle.

If you need double duty for family etc, then try something like the Nissan Navara 550 (if they are actually sold in the US).

Remember, in towing, torque rules ...
