I guess I'm the exception to the orange plastic leveler blocks crowd. I feel they're a waste of money. I got a pressure treated 2x6 or 2x8 and cut it into short pieces around 12" to 15". I have maybe a dozen or so. I can use them under the tires to level the camper or under the stab jacks or the tongue jack. They cost A LOT LESS than the orange "Lego blocks", they're more rugged and if one does break or gets lost, I don't care because I can make more for very little.
Probably the most important 'must haves' for us are:
Big, over-sized camping recliner chairs
A adequate sized awning (16'+)
A camp mat to go under the awning
Plenty of foam can coolers
More than enough of your favorite cold beverage. (Not necessarily alcoholic)
Plenty of friends and family
Every thing else is secondary to those.
