They are huge pull through sites. A 42' will fit.

I cannot say, but look carefully at site details. We stayed in a pull thru, we are 35' 5th wheel and 22' pick up and still had room to spare. This was Nov. 2019, not sure if things have changed.

No we have a 40ft 5er plus our tow vehicle puts us at 60ft most of the sites are giant. We were in site 33 they would definitely fit.
