Thinking about picking up a dual hitch adaptor
like the one pictured in the link so that I can mount a bike rack and
flat tow our Jeep Liberty (with Roadmaster Sterling All Terrian tow bar).
While I think
there's enough clearance - both in terms of distance between bikes and front of the jeep - as well as between the tow bar and the bottom of the bike rack ... I haven't really had much opportunity to observe the range of motion that the Jeep moves thru when our coach is underway. I can't say with certainty that a sharp turn won't put the bike wheels in contact with front of the Jeep. Nor can I say with certainty that the 4" distance between the lower and upper receiver is enough to prevent a steep driveway from dropping the bike rack low enough to interfere with the motion of the tow bars.
Anybody with experiences using a dual hitch adaptor like this run into any of the problems I've descried?
