I just installed a Carefree 'Camp Out' on my truck camper Palomino SS 1500.
The camper is pretty high on the truck, even down so a 'stool' won't work (can't reach the awning to deploy it anyway). My wife bought a retractable aluminum ladder from Walmart that dies the trick.
I had a Carefree on my Lance so I knew it was a well built and easy to set up awning, with excellent extruded aluminum, telescoping rafters and legs and the camper attachment points were cast aluminum brackets and stout.
The issue was price. The Carefree's are quite a bit more expensive than the other brands but I found that RV Country had some great prices so I bought one.
Forest River provides a full length awning rail on the right side of the Backpack so I sprayed on some silicone spray and slid the awning in (went in like hot butter on a slice of toast and following the instructions, attached the brackets to the camper side (must be in line with the sewn in rafter loops on the backside of the bag when positioned in the desired spot in the rail and level to the camper body.
I measured down from the rail at 2 down points at each end on the camper (in my case 56" and then snapped a chalk line across the points. I set the awning in the position I wanted it and use a plumb bob, (camper must be level front to back and use a carpenters level, don't guess) and marked the intersecting points with a grease pencil and mounted the camper brackets with clear silicone on the backs (to prevent moisture from getting in) using the supplied hardware... Mark the screw holes with a grease pencil and make sure the brackets are square with the camper sides.....
I can reach the awning with no issue with the top down using the retractable ladder. I unroll it before I raise the top and let it hang, then raise the lid, set the rafters, tension the awning and set the uprights in the camper brackets. Really, no issue other than a retractable (telescoping) ladder job and the ladder stows nicely in the camper and has 1001 uses at home too.
I'm quite happy with the price ($289.00) delivered and it's a quality awning.
Don't forget to install a screw through the extruded awning rail at each end to keep the awning from sliding in the rail when you drive down thew road. Carefree recommends through the rail and through the nylon rod that secures it in the rail. I put the screws at each end on the nylon rod and not through it, but that is personal preference.
IMO, a retractable ladder is a much better option than a step stool. just my personal preference, but I also use the ladder to get in and out of the camper itself. The camper sits plenty high on my 4 wheel drive truck (see the pictures in the truck camper thread in this site....)
That isn't me in the picture (with 2 beers), that is a friend and the awning isn't installed yet on the picture) but goes on the side shown with the push out window....
