We have a 1984 29' Fireball camper. We also have some land in the mountains near Denver (40 miles from home). We want to take the camper and set it up on the land, but do not know if our Bronco (full size) with a stock step bumper will do the job. It is uphill all the way, some of it at a pretty good grade. The main concern is whether the bumper will hold up. Any advice on this, or references, would be greatly appreciated. Thank you, Jim
