Letting Logging Trucks Pass

I think you handled it the correct way. I used to drive log trucks in BC and would appreciate when RVer's or others for that matter would do that. The whole point is that is is safer to help the faster traffic to go by when there is a good spot because they will go by eventually and it may not be Ideal. It is easier to deal with them after they are past then to have them up your butt. Even if you are doing the speed limit if there are ups and downs on the road it can cause the driver behind you alot more gear changes and hence more work less fuel mileage and aggravation.

I always blinked my lights at people like you but alot of that has changed over the years like everything else. Really is it that big of deal anyway.
Relax and enjoy the ride because most of those truckers wish they were in your shoes.
