I'm going to be using it this summer up in New England, so the heat isn't too bad here but after that I plan to hit the road and travel around the country. I have family in FL, so I'm sure I'll be stopping by there from time to time, but if I can help it, it wont be during the summer. I plan to spend a decent amount of time traveling around out west.
I probably wont do the 4x4 conversion right off the bat. I'd do it where I have access to a nice shop down in FL. I'm also most likely going to keep it on the tame side and not go with a crazy lift or really big tires. I'd like it to be functional but still somewhat affordable to drive.
As far as the E250 vs E350 is there a difference in more than just the suspension? (ie did they use different transmission or something or is it just for the better rear end and so on?)
