Welcome Newby47, you'll get plenty of good info and advice here at iRV2
I'm pretty new also, and have received much advice from other members! Fuel mileage is a hot topic. If you use the little search box w/ "find" (at the top of the posts on each page), then search with words like mileage or mpg or fuel, etc. you will find many current and interesting posts. And you'll hear from plenty of others, I'm sure.
