DO not use ladder as an anchor point.
RV ladders are marginal at best for vertical weight bearing.
Horizontal/pulling forces will probably bend ladder or rip it away from mounts
Motorcyle lift should be stout enough but like you said..........too short.
Maybe modify lift to accept a 2" square tubing long enough so that with lift raised up top would be high enough. Attach an anchor point
A weld shop could make one in couple hours.
High enough anchor point is issue...can't go around driving cleats into trees :E
A BRISK heel/toe walk around campground, stair stepping, elevated pushups using picnic table, good ole military calisthenics (pushups, squats, lunges, heel raises, jumping jacks, crunches etc)
No excuses just because of MH and FTng.
Is it time for your medication or mine?
