I travel full-time with my wife and three kids in a 40' fifth wheel. The rear of the fiver already has my Zuma 125 mounted to it. So, I opted for a Thule roof rack with sidearm trays. The truck (Dodge Ram Mega Cab Dually) is a monster! The two adult bikes will be stored out-board facing front. The three kids bikes will be facing to the rear in the three middle channels. I had to install them this way due to the truck being so massive. I can only reach the three inside carriers from inside the bed area. Pictures will have to wait until next month; that is when we leave the Mojave area...
