It is much safer than using jacks and jack stands. The coach can't fall off of it's own tires.
Don't forget to loosen the lug nuts before rolling onto the ramps.
Absolutely do NOT FAIL to use SUPPORT STANDS, regardless of whether you leave an axle in situ. The increased load on the one axle/wheels, while logical, ...is not foolproof, and although unlikely, that single axle/wheel combination can fail under the increased weight. Also be certain to CHOCK the remaining axle to avoid rolling.
ALWAYS use support stands.
Leaving the trailer connected to a vehicle is also poor practice unless the vehicle is LOCKED, CHOCKED, and DISABLED.
Sorry to be the safety-nut. But if it can go wrong, it might. (4-yr old nephew once started the standard-transmission truck with a cousin beneath the trailer releasing safety-chains from the loader. Cousin was injured in his haste to get from beneath the trailer, and the entire rig shot down the hill in reverse and ran into a tree wiping the open drivers door around to the front fender. Amazingly the 4-yr old was unhurt.)
