We recently bought a Pop-Up Camper. My original plan was to have a hitch reciever welded under the rear bumper and then use my 4 bike rack that we use on our SUV to haul the bikes on the camper. Well after reading some message boards for Pop-Up Campers (yes they exists...) I found out all kinds of horror stories about people trying it. Sounds like too much weight on the back of one of these things is really dangerous when towing as they will fish tail.
So we started searching for roof top bike racks for pop-ups but they range from $300-$400 dollars and some don't look all that different than the one I built myself today.
So a trip to Performance for 4 fork mounts and a trip to the hardware store for a 2x4, an anti-slip rubber mat that I cut up and heavy duty ratcheting straps all for $67 dollars and now I have this.
It is completely solid. The front straps down easily. We off set the fork mounts so the bars can overlap. Since the bikes have different wheel bases and tire sizes they require 2 straps.
Maiden voyage next weekend. Hopefully I won't be adding any new horror stories of my own to those other boards...
