Check out 1UpUsa. I used their Super Duty 2 bike tray rated for 75lbs per tray for 2 bikes...and I've actually added 2 more trays and hauled 4 bikes. My Ebikes are heavy. About 75 lbs each. I added their RakAttach system and optioned it to swing to driver side but I can easily get in and out of the camper without swinging it. I understand you have a rear slideout which would make things more interesting. My towing system is the Torklift Superhitch, a 42" Supertruss extension, then the RakAttach and the 1UpUsa Superduty tray. I cant figure out how to do pics or I'd attach them.
