Pulled a Wilderness 27X TT South from Palo Alto to Hwy 1 and then down to Big Sur and south with a '98 3/4 'Burb and was able to keep traffic off my bumper.
I have also pulled a Cougar 304BHS TT with a PSD Excursion and driven my 40' Tradewinds and toad north from Monterrey up 1 to S.F. and only had a problem where they were building the new bridge over the headland.
