I think it is somewhere in the neighborhood of 17''. Call
Casita at 1-800-442-9986 and ask for Jay or Susan. They can tell you in an instant. Listed are some things below that will have an effect on your permanent height, but
Casita is the best source for now.
NOTE: Two things to consider
1. Tire size on trailer (13's or 14's)
2.
Axle (high lift or regular)
Also, if your tow vehicle has self leveling load system, be sure to check it when the Engine is on and you attach while running. (or something like that as it makes a difference)
