Agree on even the tiniest little bit of fabric being caught in the bunkend seal and quarantee you'll have leakage. If you're not already doing this, make the close-up a 2-person job....poke all the fabric in, close slightly, the fabric that slipped back out - poke it in again, repeat until you can be sure it's all in there.
Re mosquitoes - door open and closed a zillion times?? Might also check the roof vents to be sure the screens are secure. Good thought on the stove vent, which you need to keep locked unless you're using it. Reason being that - another guarantee - it'll disappear one day between where you were and home. Not inexpensive to replace that little piece of plastic, so keep it latched. You might try an area spray product before you set up - early on with our HTT, we camped at a local small lake CG and the site had some low spots which had held water....water was gone, but truly, as DH backed into the site, the curb side had to have had a thousand mosquitoes swarm all over it. Before opening the doors, he unhooked and made a Walmart run for some spray and more bug candles. Don't camp there any longer. Mosquitoes nesting even if you don't see the standing water is a PITA.
Hope you can resolve these issues....know it's frustrating.
