As a few have said, you just have to take your time and make sure you tell the campground your total length (not the box length). Our 38' TT (total length) is not easy to get into narrow sites with narrow roads, even though they say it is a 40' site, it is still challenging. I have a 350, crew cab, 8' bed which makes it a touch more challenging than yours. I have had to ask a few people to move their cars as I just could not make it out or in.
Our previous TT was 32' total length and it was much easier to get in and out and we never had a problem getting a site.
I will now always pay extra for a pull through if possible.
