A low-profile, swing-up jack is common to avoid dragging on steep driveway aprons. A standard ball coupler is used, but the focus is on a secure, rattle-free connection to protect the valuable cargo. For towing behind motorhomes , specialized couplers are used that connect directly to the towed vehicle's frame.

A sturdy, simple A-frame crank jack with a wheel is the workhorse. It needs to be reliable for multiple hitches/unhitches per day. Fold-down tongue jacks are common on smaller utility trailers to save space in crowded yards.
The standard 2" ball coupler dominates. Key features include easy latching and durability against constant bumps, weather, and occasional overloads.
