Umm.. impressed with the HP and torque of a 4.0 isnt saying anything..
I have the 4.6 V8. And it has to rev to 3K rpm to go up slight inclines and to get up the steep hills to my house over 3,000 rpm... The suburban.. 2,000 rpm to climb hills...
Here:
Towing a 1989 Correct Craft Martinique on a Tandem trailer. Boat: 3,200lb dry, trailer: 1,000lbs.
4,200lbs + 300lbs of gear and water logged in the boat (all boats get water logged) so 4,500 lbs.
And as with 90% of boat trailers the hydraulic brakes havent worked in years...
+Family of 5 and luggage for all for a weekend.
Suburban in tow/haul: rev to 3,000 rpm for getting onto highway and maintain 75 mph with tow/haul in OD at 2,100 rpm and down shift 3rd at 3,000 rpm for hills, brakes keep up no problem when stopping.
Explorer: Rev to over 4,000 rpm to just get onto highway, can barely maintain 65mph with OD OFF (wish Ford would learn what tow/haul is...) and frequent down shifts into 3rd (over 4,000 rpm) for the slightest inclines and hills. Stopping, holy crap are there even brakes on this thing???? oh yeah.. NON VENTED REAR ROTORS and tiny fronts...
Yet both cars are rated to tow 7,000lbs no problem.. Both cars have the tow packages. Suburban is configured for 14,000 lb GCVWR with 4x4, 3.73 rear end, and 5.3L engine. Explorer is rated for 12,000lbs GCVWR with 4x4, 3.73 rear end, and 4.6L engine. The explorer is not ready to properly handle that 12,000lb GCVWR.
