Be sure to look around all the bottom of the tent flaps and where the the tent bed pulls out when setup. It was so bad on my tent campers I could see daylight thru those places...
I used the 2"x30" window foam strips (WALMART) that come with house window unit air conditioners. Placed these all around both tent bed sides where the flaps attach to the trailer frame.
Then I found a bigger rubber seal to put in place of the flimsy rubber seal that came with the trailer. I mounted this to the top of the frame of the trailer where you pull out the tent bed ends. i had to cut a couple of places to allow the steel guides to pull through ok... I could see daylight big time in this area...
It looked something like this...

We also had alot of holes cut in the flooring for wiring that did not have any weather seals. I filled all of those with RTV stuff...
Also we always have a couple of lights shining up into the trees away from the camper to draw all of the outside insects over to that part of the patio area. My LED strips around my awning does real well not attracting insects when on...
I have good friends that live on the East cost around Charleston South Carolina where they have the little bitty mosquitoes. Seems like they can fly right through the screens and not even slow down haha... My good friends that live inland near the Edisto Beach area always have to put on insect head gear just to go pick tomatoes from their garden. Camping right on the water is great as there is always a strong breeze coming in from the ocean side...
