Completely agree. I do have a 3 bike hitch mount as well. I was more thinking the occasions when I want to carry a few buddies with me and their bikes and gear, I can have more options and mounting points since now I can safely carry 5 people. I can also see taking a vacation with the girlfriend and wanting to haul the dual sport on the back and a couple bikes for cruising the towns up top. So I went ahead and welded tabs for 2 Yakima Blockheads. I'm thinking once I get my lift done it will put my overall height with the fork mounted bikes up top around 11 feet. So yes I'll mostly have to be concerned about low branches pulling into mountain bike parks and avoid the fast food drive throughs.I'd look at a receiver/swing out mounting system for your bikes; the combination of risk of injury/damage carrying them up there, the crazy amount of height when they are up there, and the PITA pulling them down just for a short ride would be (for me) too many cons..
