you live in colorado and you are not looking at a true 4x4,
first you get insurance discounts for 4x4 and you will be a whole lot safer on the road,
something like this, room for the family, and camping, tow a boat and get home no matter the weather, a bit more than your budget, but I know the owner

, I am sure you can work something out, no timing belts to change and 18-21 on the hwy depending on how you drive it hand calculated
