Sizing a bay for your camper
Measure bumper to hitch, not brochure length. A 'thirty-foot' travel trailer is frequently 33 to 34 ft with the tongue and spare carrier, and manufacturers quote box length. Add two feet of working room so you are not inching in with a spotter every time.
Height is where campers get turned away. Most travel trailers sit 11 to 12 ft tall with the A/C shroud and antenna; a Class A with a roof rack can push 13 ft 6 in. Our covered rows carry 16 ft clear height and indoor bays run 14 ft, which covers essentially every consumer RV.
Width matters for slides and awnings even when they stay retracted. A 12 ft wide bay gives you door clearance on one side and room to walk the other, which is the difference between loading the rig comfortably and turning sideways past a slide box.
