I have a little 14 ft travel trailer, so space is at a premium. I like to use a Coleman 4 person Insta-tent as a storage "building". It goes up in minutes and can be folded up and back in the storage bag in less than 10 minutes by one person. I don't bother with the guy wires. It weighs less than 20lbs and fits under the dinette or in the storage space when we travel. It does have a floor. There are windows on three sides.
I usually put it behind the TT. The outdoor furniture, medical oxygen bottles, fishing equipment, bikes or kick scooters go in it at night or when we leave the campsite. Equipment stays dry and out of sight - no one has ever bothered it, either.
DH has difficulty sitting at a picnic table, so I keep a little 4ft folding table and folding chairs to use when we eat outside. We always travel with a $15 box fan to use outdoors if we camp where there is electric. We can easily clear gear out the tent, put the fan in the tent with the windows open, and it becomes a good dining room option. That is especially nice in a site with no shade. The air moving in the tent keeps the bugs down, too.
The tent was $100 at that big box store. It is much more useful to us than a canopy.
I like it because it is small and unobtrusive. But, I am really tempted to go with the Ozark Trail 8 person instant tent for our longer stays. Since it is twice the size, I could leave our gear on one side and the table and chairs on the other side. You may want to take a look at that one as well for your workkamping needs.
