Let me add a few more...

ditch the air mattress or foam pad and get one of those twin/queen/king
(depending on the size of your tent) air mattresses that inflate to
5-9 inch high. They take regular-sized sheets and blankets. Quite
comfy, and are higher off the ground.

Ear plugs are great, but so is a CD or MP3 player with earplugs or
lightweight headset.

In the back of the putt-putt I have a couple of those plastic crates
sold in hardware stores and office supply stores.Really sturdy. When
I'm flying with weight in the front 2 seats, I put the 8 gal. water
tank in one of them. The other one has the tie-down kit, tools, etc.
Turned over, they make great "night stand" or small tables to keep
things off the ground. And I think I'm going to bring the 3 gal.
water tank along. Much easier to refill the bottles for the day as
well as having "clean up" water handy.
