We just returned from a 16 day, 3,200 mile 10 State tour. In the past, we found one of those 150' long pull thrus in Frankenmuth, MI but on this trip, our experience was the opposite. We only once had a pull through that was comfortable (we are 60') All of the others were either very short or were backins.
I agree with the other poster who said that the older the CG, the more likely it would be cramped. Also, we tend toward State Parks rather than RV resorts and the SP sites are normally always smaller. We did find a pull thru at a COE park in Lake Hartwell SC where we could have parked two of our rigs and had room leftover.
