DIY Door Awning

pvc it is , thanks!

aye pvc ... comes in plumbing white or electrical grey, or whatever color of krylon fusion you need.

I would use pvc, not pex. Slip fittings, can be glued or not (I've done frames with set screws).

Thanks for the comments, Before I concede and just buy one, I thinking of using some of GordonThree's suggestions. I like the removable concept instead of a permament mount. Although the aluminum tubing is light, pex tubing is more forgiving and has flexabilty. The fabric I think will be a type of nylon or rip stop with some waterprrofing applied, The shape of the frame would be halfround. In addition I think that a center arch suport to create tension on the fabric and it should eliminate any ponding on top of the awning.
As far as the mount, I thinking (this is where the real engineering is) a type of spring tension hinged-rod that the ends of the 1/2 round frame would attached to. The spring tension would create a force to make the awning want to flip up, I will need to plan some type of counter weight to make the awning level out over the door. Will need to see what type of nicknacks the DW has to hang off of the front. Throw a set of rope lights inside the tubing for nightime illumination. ok maybe I'm getting carried away, but whih 50" of snow on the ground and the MH in the shop for new balljoints, I need some disttractions
Always appriecate any additional comments or new ones. Yankee ingenuity is a past time of mine with many concepts that sound good on paper that are ineffective, but some are really cool and out of the box that work great. Have one of your own? share it.

I was thinking, a fixed frame might work too, since it's going to be a small awning. If you're parked at a site for days/weeks, Rather than roll it up when you're done, you just unhook it and toss it in storage.

Fastenal or another industrial supply will sell aluminum tubing. Get 1/2" tubing and fill it with sand, then use an EMT conduit bender ($20 bucks roughly) to shape it into a rectangle a little wider than your door and however long you want it.

Stretch some vinyl or canvas over the tubing and use aluminum pop-rivets to fix it into place.

Above your door, mount some brackets that are "open" on the top, so you can drop the frame in and lift it out. Lastly, use some paracord or whatever you see that looks good hold the frame "up", go from the two outer most corners to a hook or something right at the roof line of your coach, adjust the length as needed to get a reasonable pitch on the awning.

Usually, OTD awnings are either lateral arm (not really a DIY project). or they use long arms to keep the slope level. The long arm models usually have a front arm that is curved to fit the coach profile.
While DIY is admirable, I doubt you would save money, unless you simply go with a tarp, some rope and a couple of stakes, which actually could be made fairly attractive, but would need setup.

I would try it....what do you have to lose??

Just buy the correct awning ! It will fit and work properly!

How about a vinyl roll-up black-out shade for the awning itself. I think big-box home centers will cut them whatever size you need.

I'm stuck on how to do the arms, other than buy arms designed for the task.
