We had our original power awning arms damaged by wind last Spring, and replaced the arms with Carefree Eclipse power arms. It is my understanding that the Eclipse power arm kit will fit most awnings, regardless of brand.
We DID NOT get auto-retract ...that is an add-on option that you only get if you want to pay more to get it. As for easy to operate, the Eclipse couldn't be easer ...it beats the heck out of a manual awning. A few of those had tried to hurt me over the years!!
The Eclipse arms kit comes with a switch on the base of one arm outside, and the normal inside switch. We like the Eclipse scissor type arms much better than the original elbow type ...they are higher and not prone to head bumping, and they take gusty winds must better (simply flexing in and out much like a shock absorber). And having that switch outside is great (there is a master power switch inside so you can dis-able the outside switch if you want). We were not crazy about the Eclipse arms at first as many we have seen put the awning nearly straight out, very high and with little downward pitch. However, we found it is adjustable and apparently those we had seen were on the highest level.
The Eclipse arms kit is pricey, but we like it better than we did the original OneTouch awning. Our cost was $1,328.95 + tax for the arms kit (special color to match our full body paint), and $75 shipping to East TX. We paid a Tyler TX RV dealer 6 hours labor to install the kit. I took them the original cloth and roller tube, and had totally removed the original arms except for the upper brackets. With a couple of tall step ladders and some good help, an ambitious handy guy would be able to install the new power arms. I'm pretty handy, but I am lacking the required ambition and good help nowadays!!
