Up to about six months ago I never heard of a "Bumper Pull" But do understand the term
Class A-B-C (motor home) Conversions et-al Pick up Campers, we all know what those are
5Th Wheel.. We know what that is
Gooseneck,,, Special variation on 5th wheel, uses a "Ball" type hitch in the bed of the truck instead of the 5th wheel and kingpin system
Travel Trailer... Has a tong, like an auto dolly or trailer, or a lawn or utility trailer, that hooks to a ball on the BACK of the vehicle
A "Bumper pull" is what I call a Travel Trailer.
