I expect you will do fine. I have a 2000 F250 SD V10 w/ 5spd. I pulled a
number of people out of ditches last winter during the snow here in
Virginia, and have hauled a Bobcat on a dual-axle trailer out of a muddy
field. Lot's of other miscellaneous towing up to about 6,000 lbs. No
problems. I'd rather have the stick as I feel it gives me more control.

All that said, the bumper-attached wheel chocks idea is interesting,
particularly if the ramp is slippery.
