We have a 35' 5er in site 41. It fits, but awkward due to the tight curve of the site. Took lots of leveling.

Cottonwood sites 34 - 47 are really large. Cottonwood 20 is GIGANTIC. My recollection of the Mahogany loop is that it's a bit smaller -- but higher up the mountain so it may have better cell coverage. We struggled with cell phone in CW 32 and were more successful up by CW 7.

I have a 28ft toy hauler that fit with plenty of room to allow us to extend our 8ft long patio off the back. With the patio extended, the camper is 36ft long.

We took a 32’ motorhome with a 10’ trailer, site MG67, pull through. It’s very tight getting in and most spaces are small but 67 was level enough for MH and unobstructed enough to use both slides. I think the site to the left would have been ok but there was a tree at that one. Such a beautiful location! Mountain bike park across the street, off road riding, Park City, Midway, Soldier Hollow are close

I don't know the exact length. My trailer about 24" and my buddy's is about 26'. Some of the pull-throughs are a bit tight, but there are others that are more open. I also saw some large rigs parked in back-ins. I'd suggest you call the Wasatch SP Visitors center for more information. It's separate from the camping area, but they may be able to provide info' or a phone # for the campsite.
