Add-a-room for a toy hauler ramp

Unless you get it through the TH manufacturer, you'll probably need to have something fabricated.

I've seen everything used from EZ-UP awnings with screen side panels to family sized tents with a fabricated canvas collar leading into the TH.

At some of the larger flea markets/ swap meets there usually are a couple of vendors that supply the other swapmeet vendors with poles, coverings and parts for the canopies used in the selling spots.

The canopies can be custom sized to meet your needs. You might look for one of these vendors or someone on line that supplies for outdoor events.They could build something to your specifications that is easy to put up and take down.

The Dometic add-a-room has zip up wall panels included, unless they've downgraded it.

That said.... I didn't like the way it sealed to the trailer, and the fabric was thinner than a cheap Kmart tent. I did not trust it to keep weather out.

This time around I may try an awning room from TheBusDepot. I still don't even have an ETA on my build though, so it'll be at least a month before I can try anything out.
