is it safe to lower the travel trailer once unhitched? My main concern is: is there a bunch of weight being supported by the hitch bar being propped up on the cinder block for the truck clearance? Will lowering it cause damage?
Yes it is completely safe to raise and lower your trailer tongue by using the tongue jack. No lowering the jack will not cause damage. Raising and lowering the tongue is what the jack is there for.
There is a difference between a cinder block and something solid like a concrete paver stone. A Cinder block is hollow and extremely fragile. A concrete paver stone is solid and stronger. I would still use a block of wood over a solid concrete block.
