add a room for a truck camper

We really like the Clam Quick-set.

Clam Quick-set

Very well made. Incredibly easy to set up and take down. With the added panels you can close sides if you like. The disadvantages are that it is pricey and when folded up it makes a long bundle.

Another recommendation for a 10x10 popup canopy with screen and/or solid walls from me.

I've watched others struggle with their "add a rooms" at camping events for years. Seems like they spend hours setting them up and hours tearing them back down. A popup canopy is up and functional in mere seconds, and it only takes a couple more minutes to clip on the sides.

Here is one I found, don't know if it will work for you or not. I hope this link is allowed.

They make one for my unit (see sig.), confining if you ask me. Screen room works better for us.

I have pitched an ez-up canopy on my flatbed trailer and used that as an added room

I don't know of anyone who makes a small enough room, but I do use a Coleman screen room. You can get them for as low as $70 at times. Right now, they are $95 on Amazon.

We have this one.
