Nice truck & camper, it looks like it will be a good setup.
You should be good with the airbags, you just have to drive easy.
Having that much weight on there definitely changes the handling/cornering characteristics of the truck, as well as taxing on the brakes.
It can be scary in a panic...
I like the airbags. I use firestone ride-rites. They are easy to install, you can leave the rest of your suspension stock, and when the truck is unloaded, you just leave about 5-10 psi for a stock ride.
When you load down your truck for a trip, you just air them up enough to level out the ride...

I finally decided to let go of my Baja Bug, and plan on replacing it with a small dual sport bike like a Yamaha Tw200 or XT 250.
I'm asking $ 2,200.00 or trade for good condition Yamaha TW200.
The Baja has served me well for many camping trips. I also get lots of thumbs up while driving...
I know you asked about a vacuum, but have you considered using compressed air to blow out the dust ?
Something like this would work with an air tank or compressor.
I like it. I have a similar setup and am looking at getting a larger hard sided cab-over camper for my trailer, as my family has just about outgrown this popup. I would think the dually tires would make it more stable but what do I know. Were all here to learn and share ideas right ?
The weight...
Im looking at the TW200 because Im new to riding, want something small & light enough to load in my pickup by myself, or on the rear hitch carrier on camping trips. TW200 has a low seat, wide tires, and sips fuel.
Im not looking at it for a commuter or freeway riding.
Mostly a bike to take...
I'm not sure what brand it is. It's an 8ft Fiberglass Boat with 2 bench seats. It was probably made in the 70's. It works great with a small outboard or trolling motor. Not the most stable platform but works well enough for 2 people and minimal gear.
