Need OIL CHANGE - North Salt Lake

Looks like a fairly civilized place, ask at the campground office, or one of the maintenance staff. If its gas, any good shop with a high door and space can help you. I used a mechanic for several years that could not get the rig in his shop, so he just changed the oil outside on his lot. Diesel, find a truck service center, and get in line. Truckers have priority.

Gas or diesel??

Did you ask the park mgmt?
How about a truck stop?
