To be honest I don't remember anyone towing a car. Every place you go is set up to handle Rv's. We took some different roads other than the Alaska Highway,,, for instance the road to Chicken Ak,,, top of the world highway was 115 miles, 90 miles of gravel, washboard,, had to drive very slow, but worth it, also scary haha... would hate to be towing a car behind on that road,,, we traveled on one other road around Prince Rupert that was gravel,,,, I had planned on taking another road that was gravel but was advised that it was rutted.... there was some repair work going on and remember we went late in the summer.... read that after the spring thaw they do lots more roadwork,,,,, we could drive full speed 90% of the time,,, most bad spots on the road were marked or you could see them coming especially frost heaves,,, do not know how well they would be marked early in the summer bottom line roads were no problem a lot better than I expected.
I'm sure you saw my post on my bicycles,,, would have loved to have them in Anchorage and some of the parks,,, note we drove a Roadtrek on that trip,, I know our 2350 is a little bigger, but think it would be about the same.... wanted ride the ferries but did not.... expensive
We traveled along with a caravan for a couple of days,,, mostly all A's,,,, they all had protective wrap around the front of the Rv's... I guess since they were following each other close needed it,,, especially on road to Chicken, you will get dirty,,,, some kind of black dirt, ash,,,, I would wash the bugs off each night,,,, sprayed washed a couple of times,,,, kept wipes to keep the windows clean mainly for picture taking...
sorry so long
