Maybe I'll just stick with the 250...LOL.
Truth is, I've had 6000 pounds in the back of the one in my avatar and it barely leveled it out.
I also always laugh when I think of a night that didn't start off so great. A bit over 2 years ago when our 5 year old was 3, we had to take her to the hospital. she'd had the flu and dehydrated herself and had to have an IV. Since I was starting to get tired at 1am or so and my eyes were getting "blurry" I went home to switch vehicles and get an hour's nap as we'd driven her there in my Mom in law's Buick and I wanted to bring the truck to pick her up as it was easier (for me) to park in the hospital parking lot.
On the way home, she very sleepily says "Daddy, your twuck is too bumpy"
So, I'd probably get a 250 but was curious about this with the 350. and of course, buying used, you never know what might come up for sale!
