Hey, GRAD, how ya been? Passed off any 'good' advice lately? [;)] Congrats on the upcoming pooping machine.
You're going to miss your truck if you get a Tahoe or some other enclosed SUV. If you don't want a big one (I LOVE my Ford Superduty Crewcab) you might consider some of the new mid-size crewcab trucks. Ford Supercrew (great engines) or the new Chevy that looks real swoopy (comanche??). I'd go with the Supercrew, though, as I've heard the new chevy is pricey. Plenty of room for the family to grow in, good rear seat room, pickup bed for the wifes' landscaping ("honey, that tree [150' Sequoia] is perfect!!) projects, great engine (already said that) and it'll pull your partyboat. Major Murphy's Dodge Dakota crewcab would also be a good selection. All the new, little crewcabs (Nissan, Toyota, Chevy S-10, Ford Exploder thingee & etc.) would end up being too small both inside and in the engine compartment.
Hope this helps.

Edited to point out that the Dodge Dakota can be had with the same engine (360 c.i.) that Jarhead22 has in his far too plush Durango. [:)]
