Can anyone comment on how a B tows a trailer like a bunk house or lees-ure light camper?

I towed with a 1700 vaquero 2 yrs & found that I was shifting on the hills, maybe the 6th overdrive at highway/freeway speeds. Unfortunately due to someone running a red light the bike is gone & I find myself looking for a new one. Have owned many Honda's in the past & think it would be a wise purchase.
