Staying at the Main Street Station RV park for 2 weeks. Found it on Allstays and it is adequate for us. The bathrooms are new/clean, security good, concrete parking, and best of all just walking distance to downtown casinos for great deals on meals. Last night we had a great prime rib dinner with salad bar, baked potato, and a cherries jubilee dessert at the California for $10. Plan to have breakfast there (11P to 9A graveyard special) of 2 pancakes, 2 eggs, sausage or bacon for $4.99. Hard to beat anywhere! Downtown is not as fancy as the strip but we are very comfortable here.
The pull thrus are long enough but slightly narrow but not bad. 50A, sewer, water, no cable/wifi for $17/day, a deal in my book. I can open my slides and my swing out bay doors to get my trays all the way out. Clean.
Do not use the coordinates Allstays gives as my Garmin was confused. What might be better is to program Main Street Station Casino and it is across the street. There is a medial strip so you cannot approach from the opposite direction.
Btw, yes it is on the distal side of town from the airport (I -15 E) but it is not too much more to not consider this site, IMHO. Vegas is not that big of a town.
Just another option, good luck.
