I released my '98 wrangler last year before Christmas to purchase a larger more family friendly vehicle. I landed a 2005 excursion. I haven't camped with it or had it trail riding, but for the trips to Sam's club and making the rounds on Christmas Day it can't be beat. THere is six in my family and the Ex is great. I like to think my Ex is just like my old TJ on steriods...solid axle front and rear, bigger stronger engine, more tow capacity, and more seating.
I do plan to use it over our mini van when our youngest is old enough to travel to the beach and what not (although the gas expense may change my mind).
I dont have a use for a pick-up all the time but when it comes time to purchase a mattress, carry many sheets of plywood/lumber, or other such items, the Ex doubles good for that.
What I think is the most benefit to a larger vehicle like this (suburban, yukon, excursion...) for a family of 5 or more is everybody has some "elbow room". It really eases the complaining, yelling and screaming, and general kid issues that arise when they sit next to each other.
