The last two times we had the following "surprise":

Woke up one morning to a huge wasp inside. Luckily had bug spray and tennis shoe handy.

Right before turning in found a yellow jacket inside. Again, bug spray and tennis shoe.

Anyone else had this happen or should I be bringing the PUP to the dealership for a look-over?

I see you live right around the corner from Maddam Boomer and Rusty, they are also in Cypress, TX.
The few places I would check are:

1. Be sure the velcro that secures your door at the camper is sealed right and as flat as you can get it.

2. The other place is at the beds be sure there are no gaps. and if you have a slid its the same way. The rubber under the bed was broken on one side and had a big space. I replaced it and cut it 1/8 longer on both sides and couldnt see any light.

3. if you have kids have them watch when they open the door and be sure to close it tight.

Last thing, close all the curtins and see if you can see light coming from any place and seal it up. I even used steel wool around the power cord and we would spray around the tires and stabilizers to stop the ants if we were there for a while.

Hope this helps.

Last two times we camped out last year, after we had returned home we found rather large spiders in or around the camper shower area. Bug spray .. never leave home without it!

The weirdest thing we've found was a bat which flew out from under the roof when we were folding our camper down at the end of a trip. It never got inside but it sure gave us a surprise when it flew!
