I just became member yesterday but been reading hear for a week. I just sold my 2007 crewmax 4x4 that averaged 15.8mpg. I put 32000 miles per year on truck and only tow a bass boat. I've owned one diesel and it was a 200 duramax 4x4 and it averaged 19mpg. It had all sorts of transmittion problems and other issues. I usually turn my vehicle yearly. It has goten to the point with fuel prices trucks and suv's are anchors and no longer hold value. I was hoping by going to a diesel I could get back to 19 mpg average and that is better than 15.8 for gas. Also I need the best resale from what I pay to resale. Diesels used to hold better but now I've been told thats out. As far as the difference between the prices I think in the near future they will be about equal and probably about 5 to 6 dolars a gallon. This is crazy but what do you do. Can someone please give me some good advise on what you think about a new Mega or quad 4x4? I like the quad looks better but the room is tight in the back seats compared to other trucks.There quad is more like an extended cab. It seems a lot of people buying the new trucks are trying to already sell them. Plus I love the lift with 35s. You can sure get a new truck now with rebates real high. Please your thoughts.
