We have a 2001 Mirada F53 w/V10. we pull a small Honda Civic.
No problems. When going uphill, instead of pushing the gas to the floor and getting constant upshift/downshift, I'll manually downshift, slow down, and maintain a slower speed, and usually higher RPMs (4000-4500). Going downhill, slow down, downshift to a lower gear, let the engine do the braking.
Highest is I-70, Eisenhower tunnel, west of Denver, 11,000 ft. Did the climb at 25-35 mph in 2nd gear, following a line of 18 wheelers.
OH YAH, Enjoy the scenery.

It won't do MACH 2, but I can get a sandwich and take a pee.
