1) Propane grills are OK, charcoal are not; Have not heard anything specific on firepits, but would imagine they may be OK.
2) Kegs are a no-no. I suppose if you kept it in the RV, it may not be an issue, but you'd do so at your own peril.
If you go away from the keg, note that bottles are not permitted in grass parking areas (which the RV lot was, as long as I can remember). If you want to play it safe - cans.
