The Camping World in Salt Lake City has water, power, and sewer and for about 6 sites and will allow camper to stay there for free if this will help tide you over.
Camping World is in Draper not Salt Lake City, it does not have but two working sites and no sewer. So check the power poles before you set up.
The Camping World in Layton/Kaysville has full hookups and six or more sites as well as a dump at the business. Both require you check in with them first and also that you have work being done.
There is a RV Park in North Salt Lake next to I215 at Redwood Road, also a KOA on North Temple in Salt Lake and a rv park in Draper down the road from Camping World.
There are many parks located in Moab which is where Arches and Canyonlands is located. Several more around Bryce and Zion. I usually stay at rv parks away from the national parks and the crowds. And you can find that most all of them have full hookups and a lot better prices when you distance yourself from the crowds.
