We have been on our first extended trip with our new to us #560. We have been learning a lot about the wide variety of camp site conditions we will be setting up on and the value of the heavy duty stablizer/leveling jack on the camp‐inn trailers. Ours was built in 2009 which means we need to use the hand crank. Question: When setting up on uneven ground are the stabilizers strong enough to carry the of the trailer and occupients or is something like the Bal‐lever something we should be using? Thanks
