The motorcycle ramp is a three piece affair with the middle section riding in the truck and the two outer sections riding on the canoe rack providing bike mounts for up to 4 bikes. The two most used bikes ride clamped to the canoe rack with the rear tire riding on the bed rail. A twisty holds the back wheel on.
We have traveled like this for five years. The down side to having the bikes outside the bed is a little more exposure, but they clean up easily. The upside is huge and that is you can remove any one bike, one at a time without having to unload the whole package. For 2016, we dropped out the Motorcycle. The truck bed ended up almost empty with all the bikes up and out. I carry 4, but with no motorcycle, I could carry several more.
I have tried the front racks, but it is very tiring to drive looking through them. Its is especially bad at night with headlights reflecting off of stuff.
For my family (down from four to just two) having the toys along is what makes the trip fun. We can only sit in front of the camper admiring the next camper for so long.
