No, the site length is for camper only. There is typically enough room for a truck to be parked next to the camper (either at an angle or parallel to the main path). The sites are smaller then what their designations are by a few feet. I usually add couple of feet so that it's easier to get in and out. If my trailer is 30 in length I'd request a site that is 32/33'.

You can park your truck horizontally in front of the trailer, assuming you have enough space to do that, and you should be fine. That’s what we did, we were there a whole week.

Yes. Two years ago Gros Ventre CG was first-come first-serve only. Double check that you have the correct CG.

I typically look of photos of the site, if available., and determine if it will work if a couple of feet short. Since sites can have different shapes, the answer will vary. If no photos are available I opt for other sites or campgrounds.

Yes. They are becoming more strict on the "stay on the pavement" rule.

Sometimes. Some sites are single vehicle wide, while others are 2 and 3 vehicles wide. If the on line picture doesn’t provide this information, contact the campground and they can provide more detailed information.

Sort of: you will get in trouble if you do not stay on the site’s asphalt parking. I was able to park on a 40’ site by raising up the back of our 45’ MH to clear- overhang the 8” high concrete curb at the back of the site. There was room (not much) to park the car besides the MH. Some people with trailers were able to park the truck parallel with the road and still stay on their asphalt.
