I'm 31.5, more like 50 with tow. Don't normally overnight in places that have length restriction. Not that I check, just not our style. Turns out some of them did. I will say I have had second thoughts on many access roads to campgrounds and remote attractions where there should have been a warning but were none. Only had to disconnect and turn around twice in 16 years and 110,000 miles.
If it is paved on the way in it is better than gravel. Also reading branch clearance and trunk rub/damage will come with experience. Be especially aware of roof top side clearance because rough terrain can cause a foot or more of unexpected sway.
Good Luck Have Fun Stay safe.
