Are the front stabilizing jacks strong enough to hold up my camper? It would be for about an hour with no one in the camper. I want to change out my tongue jack.
Looking online at jack ratings, the lowest I could find for scissor jacks is 5,000lbs. (Assuming you have that style like most newer trailers) It doesn't specify if that is each or for the pair, but either way they will be more than enough to support the tongue weight of a large tt.
As long as the tt is blocked on level ground it's not a problem.
