We do that very often at state parks. Actually, we often "drive in" vs. backing in to get a better view, a little more privacy from traffic, etc. The sites are not Full Hookup (Electric, Water, Sewer) just Water and Electric.
You'd be likely to need an extension cable for your Electric. $30-something for 30-Amp which a Class C usually is. Probably an extra white water hose $10. Trying to hook Sewer up would be dicey, to get it to still flow. Hard enough when you're on the "correct" side.
Get there, make sure you can do it, then make a WalMart run.
