Question: Can you use this bike rack if you have a spare tire on the back of your camper?
Document: This was just what we looking for. We had to put the bars that hold it on upside down to get it to work with our bumper but it's just fine. We also had to take the spare off the back since it was in the center of the camper. We have to carry that somewhere else but knew that before we bought the bike rack. Glad we got this one instead of a tire or ladder rack.
So-put this on the back of our RV. It is a sturdy bike rack. Fits well and adequately supports the bikes. Seems like it will survive the flex and bumps on the back of a towed camper. Thought I would have to remove the bumper mounted spare and carry it in the tow vehicle. With a little ingenuity we designed and built a spare tire mount that fits between the two bike racks.
This rack worked perfectly for us---we used it the first weekend we got it. It wasnt hard to hook onto the camper bumper(we had to remove the spare-tire) You have to make sure you tighten it properly and use a strong bungee tie or rope to secure the bikes to the rack. Pre-fit the bikes on the rack before you do the final tightening---just to make sure its positioned properly. We didnt have any trouble what so ever with this product
simple design using apropriate materials this works. my spare tire is mounted to the rear of the camper shell not to the bumper and since the inside bicycle tire is 6.25 inches farther back than the bumper, this works without moving the spare tire in my case.
I bought the Swagman 2-bike RV Bumper Rack after reading the two other reviews. Yes, I did have to remove my spare tire, but that was OK. I am a woman RV owner and I was able to install this rack with out any  problems. I travelled from Northern California to Palm Springs and back with no problems. I highly recommend this bike rack.
I had to install the rack below the bumper and leave the upright post off because there wasn't enough room between the bumper and back of the rv. I was able to leave the spare tire on but had to remove the cover. I strapped the bike to the spare tire and bunged it to the rack, ladder and awning post.Well made, nice fit & finish. You need about an inch between bumper & rv to install per directions.
Just like other reviewer said the handle bars of first bike hit the back of the camper which in my case is all window. Not good but easily fixed. Had a spare 8" eye bolt in the garage. Bent the eye over in the vise at 90 degrees and then mounted it in the hole already in the top of the stand up brace. Added some foam and duct tape and now it keeps the bike from hitting the back.
The two bike Swagman I bought from Amazon fits perfect on the 5th wheel bumper. The rack is SOLID and the bikes fit securely. I use bungees and straps and a piece of pipe insulation on the end of the handle bar to cushion against the back of the trailer. My bikes are expensive so I wanted a rack that would keep the bikes from bumping into each other causing damage. Can't believe how inexpensive the rack was. Very easy to install.
this is the only way we could haul our bikes. We did have to take off the spare tire though. Bikes do tend to rub together so we really tie them down and put padding between parts to stop them rubbing.
This bike rack was very, very easy to install. When I put my bikes on it for traveling and strap them down there is no movement at all. The only thing I had to overcome initially was that the handlebar for the bike closest to the camper would lean against the back of the camper. I eleminated this by placing the inside bike in the closest rail to the bumper so it leans toward the rear. After this minor adjustment it really works great.
