I parked my 21 foot motor home in a huge spot and flat that would have easily accommodated a huge rig like yours. This was site 19 and I just added a photo. Your big issue is the tight turns in the back loop, I don’t see how you would maneuver but you could avoid that back loop by entering the other direction. Call the ranger office for advice. I notice that for this campground there are not driveway length descriptions listed for each site in at the reservation page. Staff at this park are very helpful and over the phone they helped me avoid reserving a very sloped site. (707) 946-2409. Or might be 707-946-1811

Our 27' barely made the tight turns just getting into the park and our spot was super tight, so I'd probably not try.

We did not drive around the whole campground when we were at Burlington but I don't think a 37 foot trailer would fit any of the spaces we saw. The reservations page says that the pad is only 24 feet.

No, our 27’ Airstream was super tight there and had to park the truck across the street. Safe travels!
