Carson City is our normal overnight stop when we head north to Oregon. We recommend Silver City RV park that is just south of Carson City (about a 1/2 mile). It is nothing special, but it does have diesel/gas pumps right out front where it is super simple to fuel up. Sites are of sufficient (but not spacious) size and fairly easy to maneuver into/out of even with our 44 foot mh plus toad. We always ask for a "far end" side....easiest to access. Price was/is $42.
They actually call it a "resort", but don't be fooled by that. It is anything but a resort.
Hope this helps
