Thank you all for your responses. The only fear I have with the Land Cruiser is the gas mileage. My last truck only got10 MPG, My wife's 4runner gets 21. I also had not thought about the sequoia. Don't know the Gas mileage for a 1st gen. Sequoia.
Sorry to hear about the EX.
We looked at Sequoias and LCs before we bought our Suburban. MPG will likely be better than your Excursion but nothing close to the 21 your wife gets in her 2x4 4Runner. We average between 14 and 17. A friend with a Sequoia tells me he never gets better than 16. And the full time 4WD of the LC will likely keep you around 13 mpg in daily driving.
Space can be a big consideration with 4 kids. We have 3 and a large dog and everything but the Suburban and Excursion just didn't cut it without hauling a trailer when camping. Even the Suburban gets a bit tight with the Engel 45 and emergency kit\bug out bag behind the 3rd row. We usually mount a roof top cargo box for the tent, sleeping bags, etc. and store the food in the back.
What about a diesel EX around 2003? You'll get better mpg and still have the space. Guess it will come down to how much interior space you're willing to give up for Toyo reliability. As mentioned previously, a Lexus version may also be a good choice as they seem to be more fastidiously maintained. Many of the Sequoias we looked at did not appear to be lovingly maintained. Looked more like well used minivans inside. :ylsmoke:
