If the bike had traction control would you not be so concerned?
This summer I pulled a trailer from Va. to Yellowstone and back with my 10 year old two up on an 06 FJR. 2014 we plan to do Va to AK.
I felt the overall ride was safer, having all the extra weight off the bike but we are considering buying a Wing for the big trip and leaving the trailer at home.
The other thoughts were a GS with Jesse bags or a 2013 FJR with traction control and the trailer.
I just can't pack for two up on an extended trip with the FJR luggage and camping.
