Shade Pro out of El Cajon installed ours in March of 2013. We live in The Inland Valley area.
I believe they are in Quartzsite during the Jan/Feb RV time. We've been going for last few years and I believe they were the ones that came to our
campsite to repair one of our friends torn awning.
Our invoice lists "Shade Pro", but it also says "Carefree of Colorado"
The installer said they are "all over" whatever that means.
We have founds some great bargains, you just have to know the real on-going prices.
