I have a 8ft awning on my 2005 2500 9.6 bigfoot. I originally had high hopes for it but I have found it to be next to useless and really have stopped even trying to use it for the last 8 years. It is only 8ft long and off the cuff 6ft deep and ends up high off the ground, so it provides very limited sun or rain shelter, any wind/rain at all and everything gets wet and straight down heavy rains the water hits the ground and bounces back up splattering everything with muddy water.
I prefer a instant up 10x10 folding shelter if where staying in one spot for few days .
