We just bought a N2U 2007 Rockwood 1640 LTD as our first PUP. Out primary purpose for the purchase was to take it to various locations for mountain bike racing. Perviously we spent 2 weekends driving back and fourth sometimes twice in a weekend to preride and race. The camper will let us stay on location for many races, and very close by for the others. Now... Bike rack options... We CAN take the wheels off and put them in the tow vehicle. Benefits there are that they are safe and secure without having to go through the trouble of locking them on to the rack. Drawbacks are that I have to lay a seat down to do this, so if we take more than our son with us, I don't know how we would fit bikes + gear + kiddo. We already have a hitch mount rack that can easily be moved from vehicle to vehicle. I saw this adaptor that allows you to add a hitch to the rear bumper of a camper: I thought, FANTASTIC! For 50 bucks or so i can just add this on, and use my existing hitch mount rack! But upon closer inspection of the rear of my camper... it would appear that the spare tire is going to be in the way. I can't even SEE the rear bumper at the center of the camper, I only see the spare tire, and some weird mounting contraption that I don't know what it's purpose is. Stock picture (not our camper) but shows the spare tire placement: Has anyone used one of these adaptors on a pop-up sucessfully? Did you have to take the spare tire off? Lastly, I've seen people put roof mounts on popup campers. Does this damage the roof? How does it effect towing with bikes on the roof? I'd love to hear some advice from others that regularly tow bikes with their popups. I guess as a last resort we could get a roof mount rack for the tow vehicle, but that's going to run us $$$$$ that I hate to spend when we already have a perfectly good hitch mount rack, and frankly, I'm not sure I can lift my mountain bike to the roof of our tow vehicle.
