Hi, George! Thanks so much for the info. I really appreciate your input. I definitely don't want a roof rack. Although I like the look of them, I don't want to lose the great gas mileage I get. Plus it would be a huge hassle for me to lift a 40-lb DH bike over my head! When I saw your pics I thought that bike rack was the 1upUSA. I read the reviews several months ago & thought it would be PERFECT for me, but it's heavy, & I was concerned a Class I hitch couldn't take the weight of the bike rack & two DH bikes. I figured worse case scenario, I could take 1 DH bike apart & put it in the back of the car, but my other DH bike (Giant Glory) doesn't have quick releases, so I would need to transport that 1 on the bike rack. The installers I've been talking to tell me I can't transport two DH bikes on a Class I hitch, but I've been doing a lot of research, & I disagree. I'll definitely check out the Curt hitch/1upUSA rack combo. I can't believe you got 47 mpg with the bikes! That's amazing!
