I have a 27 foot camper and an old 1986 Suburban to tow with. The Suburban tows wonderfuly but gets about 4 mpg ($1. a mile!). I was set to trade for a 1999 Suburban with a 350 engine and a V-8, 1/2 ton. My husband informed me that someone at work said it wouldn't pull as well or get as good of gas milage as a 2500. I have tried to research this for hours and am only more confused. We usually camp close to home, so the towing is minimal. However, we would like to take some longer (3-6 hour trips) so we need soemthing more fuel efficient. We have 3 kids and the older 2 like to bring friends, so we need a third seat. Does anyone have any feedback that would be helpful to me? Thank you.
