Has anyone ever put wheels on the 4 jacks to assist in loading the camper? I'm thinking about putting 3 inch steel swivel wheels on the jacks to help me get the unit straight when loading it.
Centering guides are a MUCH better idea, they're a good idea for every camper. Campers tend to walk around a bit, guides keep them in proper position without having to get too crazy-tight on the tiedowns.
