We have a Jayco Recon zx 5th wheel toy hauler:radio I just finished installing a Tarheel ll screwdriver antenna up on the roof I have it clamped to the ladder mount and will fold down to lay flat while driving the wires are run down to a vent in the garage area their was enough space between the grill on the vent and the cover to close it with the wires running threw it. the radio a Icom 730 I set it on the work table which folds up when not in use. I am very impressed with the operation of the antenna it works just as they claim. Have had many good reports with it.
