Thanks, everyone. I appreciate your inputs. I've never towed with a hitch extension but my thoughts (and fears) have been reflected in your responses. I guess the need for a hitch extension is the crux of truck camping with a SB when your toys need a trailer. But that's what I have for now.
Please keep the comments coming about towing with a TC.
As for getting a lighter TC, does anyone have any comments about the Adventurer 80GS? I know Bigfoot campers are well respected for cold weather camping, but can an Adventurer - and its occupants - survive the snow?
Thanks!
