I was getting 14.0 pulling a 31' 9600gvw med profile 5er and we just bought a 32' 15k gvw hi pro 5er and mpg went down to 11.5... GGRRR! It could be worse, tho. 18 - 20 empty depending on city or hiway. Just got 18.27 @ 75 mph (we didn't have any time to waste) on a long road trip empty. Why don't you want a dually? You'd change your mind if you towed on a windy mtn road with one. Mine is just as stable with the 15k 5er as it was with the 9600 5er. My srw felt like a boat even at max tire psi. I've had 2 srws and 2 duallies and I won't go back. Craig
