Regarding low limbs at ny state parks and DEC campgrounds. Many people call them "state parks" but some are managed by the Department of Enviromental Conservation (DEC) and others by the NYS parks department. This makes a big difference on how the parks are run and managed. Watchout! Most NY run parks in the catskills and adarondacks are run by the DEC. They do not believe in trimming trees in parks or along the access roads. I booked at a park in the Catskills a few years back and have camped in the adarondacks. My trailer is 32' pulled by a Ram 3500. The site was big enough but getting in was a night mare. The road in the park was about 9' wide with trees and bushes along both sides and the road was one way only. The only way i got trailer in was to pull into an empty adjancent site then back in.
Most of the time we camp in the Adirondacks but will be staying away from most parks there as the DEC does not like to maintain clearance and when they design a site just leave the stump in the middle of the entrance to site. Many of the DEC campgrounds were designed and built back in the 50's and 60's and never upgraded.
Those parks that are run by the NYS park service are much better all around. DEC believes in very rustic. The park people on site agree with ones concerns about trimming, etc. but their hands are tied. A NYS arborist has to come inspect any tree before a branch is trimmed.
The sites one selects is big enough for your rig but getting into it can be a major PITA.
Happy Camping
