Does anyone have a popup like I have, or one form the same family or similar construction? (I think many or most of the Forest River models have similar construction). The roof is all fiberglass, and I don't want to drill into it The tow vehicle is a 2013 Subaru Forester. It would be tough to squeeze anything in between the tow hitch and the tongue. The roof of the car usually has as many as three whitewater kayaks when I go some place, so I'd prefer not to have a car roof mount if possible. I could move the kayaks to the camper roof, and tie them on top, but the roof mount works better, and once i arrive, will carry the kayaks on the car roof. I saw a spare tire bike rack listed, and am not sure how well these work. Here's one example: https://www.amazon.com/Yakima-8002599-SpareRide/dp/B0171A6MSU?tag=gearingout-20&psc=1 Does anyone have experience with these, and if so, what model/manufacturer do you prefer? Does anyone have another alternative?
