RTT While Keeping Use of Diamondback HD

Will be purchasing a diamondback HD this week and also want to get into the RTT game. Thing is, I don’t really want to lose the use of my bed from putting a RTT on the diamondback and can’t afford an overland trailer right now. Any suggestions? Anyone on here put the RTT in their actual roof? I’d like the diamondback for the water tightness and security, but it seems like people have a much easier time with bed racks and going without a tonneau for overlanding/camping. Any suggestions?

 

I use diamond back cover and voodoo bed bars. Gear stays locked and dry, plus the bars come off easy for daily driving purposes.
