Hi Kevin - the awnings are made by Carefree of Colorado. The exact model and serial
Nber can be found on the forward arm of the awning. If you open the awning up you'll find a white tag stuck on the underside of the front arm. I can make a copy of my manual and email it if you'd like. For the time being though, you're on the right track with the adjustment. You need to push both pins in at the same time, they are a bugger and I would suggest using two Phillips screwdrivers to push with before your fingers take a nasty pinch, and slide the arm to adjust it. Word of caution on the motorized head on that arm. Be sure all screws are tight! Mine loosened up and caused the gearing to go bad. Components are not available! Head assembly only - for over $300! A little maintenance on that each year (pull apart, lube, tighten up) will go a long way.
