Seems like you have all your "wants" lined up, which is good. I dont know if all bumper pull TH's come with the same amenities as 5th wheel TH's, so the only thing I can think of is if I was to do it over again I'd make sure the garage floor was NOT a dovetail. Only because I liked the idea of using the garage door as a additional floor up off the dirt/sand but having the dovetail portion is minimally inconvenient. Especially if considering the tent which attaches to the door area and turns the door into additional sleeping area. Other than that.....hope you find whatever you're after. :)
