I have installed a few awnings on RVs, both as a side business and on my own RV. It is not a difficult job! When measuring and drilling, I use duct tape to hold the track in place. I triple check position and measurements, and drill! Remove the duct tape, add Dicor sealant tape the the back side of the track . Dicor is available at Amazon.com : https://www.amazon.com/gp/product/B0...?ie=UTF8&psc=1
After the drilling is done, I follow these procedures:
1. Call a friend to help. Bribe him (or her) with beer!
2. Have the friend hold one end of the track while you put in a screw on your end.
3. Send the friend for more beer while you put in the rest of the screws.
4. Have the friend hold the arms in place while you measure and mark their positions.
5. Drill, add Dicor tape or putty and install. DO NOT OVER TIGHTEN!
6. While the friend is supporting the roller tube, slide the fabric onto the tube, roll it onto the tube and attach the support arms.
7. If you have any more friends, invite them for a beer and put them to work!
8. While 2 friends are supporting the arms, 1 friend stands on a ladder feeding fabric into the track while you are on the roof (or another ladder) pulling the fabric. Assuming you don't fall off the ladder, this takes about 5 minutes for an 18' awning.
9. Attach the support arms to the RV.
10. Roll out the awning and add tension to the torsion springs. While a friend supports the end of the awning, remove the awning tube from the end of the tube with the locking mechanism first, add tension (use visegrip pliers) and lock in place. Re-install it on the support arm. Go to the other end and add tension and install it on the support arm. BE VERY CAREFUL! The torsion springs can hurt really bad if you don't keep control of the visegrip pliers!
CONGRATULATIONS! Celebrate, because you just installed an awning in about 1 1/2 hours...and had fun with friends!
CAUTION...don't drink too much until after the job is done or you may have to finish the next day!
