Camping at Hobbs (USA): Frugal or Folly?

Need PIREP on tenting at the Hobbs Standard Nationals.

We're driving out next week for our first trip to Hobbs since before
our 10-year-old twins were born. On the last trip, my wife and I slept
in the van out on the ramp: cool nights, steady breezes (no bugs), no
issues if it stormed, etc.

Sleeping in the van is no longer an option for the four of us so we've
been tenting at contests. I've heard that the campground across the
road from the SSA is nice (it was a new field of mud the last time).
Also that there's some grass on the airport (all I recall is
concrete--acres of it).

Any reports/opinions on putting up a tent when we get there?
