there are 34s that have made the trek to panama and back.
going SLOWLY over road irregularities with a triple axle...
often means 2 outta 3 tires are on the ground, articulating over HOLES and stuff.
whereas a single axle unit would be ROCKING and HOPPIN'
i've been into some places a 34 clearly should not go and made it out ok.
the 2 biggest issues are...
1. road NARROWNESS (like on the really tight turns) or limitations caused by TREES...
2. traffic (meeting others going 2way on a 1way path) or backing issues in traffic.
and a place to turn around (ok that's 3 issues)
i see NO WARNINGS about trailer length at that campground ((looks like a good place to VISIT too))...
and the 'average parking space" size of 15x45 is pretty darn big.
usually if there are SIZE issues, that will be mentioned many times over in the park description.
call the ranger station and simply ask..." are there and size issues getting IN or OUT?"
and keep telling u self "a 34 is really just a 31 inside"...
