The gang at Tough Top Awnings were great. Extremely helpful and always returned a call. Videos on their website were very helpful. Both replacement covers fit perfectly - I did the slide by myself and had my wife and a good friend help with the main. Materials are top-notch!
I would not hesitate to recommend them to others.

Fast Shipping--Great Packing
OK, here goes. I'm 75 years old and describe myself as an OFBG (Old-Fat-Bald Guy). Although I'm slowing down, I still do most of my own mechanic and home maintenance myself.
Today, I started the replacement by watching one of the videos two times. I figured I had it down. First thing was to extend the awning about one foot--as the video shows. My RV is a 29 ft class C. I determined that removing and reinstalling from the rear would be the optimum direction. I continued with all the steps as per the video. Then it dawned on me--"I have no help!!" No turning back now. So, I did the pick thing and removed the spring end thing and counted the turns. I lowered the awning to a pair of saw horses and then cut the old fabric from the top. Lots of ladder moving and climbing. Removed the screw that locks the fabric in place and pulled the fabric out--to the rear. So far, so good. Then I cut the fabric near the roller and pulled the fabric forward off the roller--to the front. Still no helpers. I cleaned the groove in the upper track and both grooves in the roller. Lubed all three with Silicone and then tried to figure a method to get the fabric into the track on the upper side of the RV. Here is where it got interesting. Still no help. I firmly attached a small C clamp to the top-front corner of the fabric (where the fabric is doubled and stitched). Remember that I am installing from the rear of the RV. I ran a rope through an opening at the top of the front support and then rearward to the C clamp. Still no help. I have finally determined that I cannot continue by myself. My next door neighbor was out cutting his grass. I asked him for a bit of help and explained that no ladder climbing would be required. All he had to do was pull the rope as I guided the fabric into the track. That took no more than 10 minutes.
After he left, I moved the sawhorses and roller rearward and started feeding the fabric into both tracks on the roller--from the front. Feed a little, reposition the sawhorses and roller, rinse and repeat. So, now I'm beginning to feel pretty good about the install. I requested my wife to come out and assist with holding the supports while I installed the spring thingies into them. Man, I cannot believe how smooth this is going. I got everything set and flipped the lever to roll it up and you know what happened---NOTHING!!! I got cocky and wound the spring the wrong direction. OK, removing the end cap from the support and rewinding the spring is not just a whole bunch of fun. It is especially not fun when you need to do it 2 more times in order to get the tension correct. Several unpure thoughts occurred during this portion. I have no idea why the 9 turns did not work, but it did not. Hence the 2 more times.
So, what is my impression of the Tough Top Awning?
I am very impressed. The workmanship is first class. The fit is perfect. The material looks great and should last a long time. My wife says that it is beautiful.
Other than the 10 minutes of assistance from my neighbor, I really think that I could have completed everything else without any help. Having my wife help after I messed up the spring winding portion just made it much less difficult.
Do I recommend attempting a similar install by yourself??? Heck no!
I do believe that more than one assistant is unnecessary. 2 assistants would be too many, and more than that would be like a government operation.
My single biggest regret was that I totally forgot to take any pictures--I know, I know--No pictures means that it never happened. To that, I will raise the BS flag. I have the sore back to prove it really happened.
Thank you Tough Top Awnings.

Great awning cover, easy to install with tutorial online.

Vary good product. Shipped fast

Heavier fabric than OEM, which made installation a little more difficult. The seams, piping, and hems all look stout, and we look forward to using this for a long time!
