well there isnt anything flat around here. im in no mountains, but i am constantly going up and down the rolling hills in western ND. that plays a big part in MPG. how heavy is that 27WP. my 295WP is 8150 dry....plus 100 gal of water, two 450 lb quads, generator, and all the other camping essentials im guessing im around 10500. i have never seen over 10 mpg with it. it likes to sit right between 8.5 and 9.0 when going 65 mph. like i said in my last post, if i pull at 60 mph i can squeeze another .5 mpg or so out of it.
