The two biggest things I have found that consistently affects me are, wind and temperature. both will play havoc with your MPG. One bit of advice an "old timer", his words not mine told me years ago was watch your weight. one trick he said he uses is to not fill his water tank to capacity if he is making a trip and will be hooking up to cg water. he said he only filled his tank about a quarter full to use for coffee, cooking and the toilet only in an emergency. water weighs about 8.3 lbs per gallon so with a 90 gal tank, just filling it one fourth full will cut about 70 gals which equals around 580 lbs. this will help fuel economy but also allows for extra cargo.
