coachmen freedom express 192rbs

Last Train - while we're on the subject of towing a trailer like the 192RBS with a V6 Ridgeline as you do or a V8 Silverado as I do the question for those contemplating a trailer like this might be - is there an significant difference in fuel mileage between these two vehicles when not towing and when towing? I typically see ~ 15 miles to the US gallon around town, ~ 22 mpg highway when not towing, maybe a couple mpg less if the terrain is hilly and/or it's quite windy, and typically between 10.5 to 12.5 mpg when towing our 192RBS - rarely if ever below 10 mpg but not much greater if it's hilly and/or windy, well into the 12s if the roads are relatively flat and relatively calm, an overall average perhaps of ~ 11.5 mpg, which is pretty good relatively speaking. In comparison, how does your Ridgeline do? :@

Also curious - with my 192RBS averaging ~ 4800 lbs loaded & ready to camp I typically run ~ 625 lbs of gross tongue weight so I'm wondering if you're running ~ 4600 lbs GVW how (and why) you keep the tongue weight down so low, ~ 11%. :h
