Nice, I have an 04 expedition too that we've had forever and now looking to make it our 'camper' and tow vehicle for our boat. We just bought a new car so now the Expedition sits while I plan... So far wife and I agree on a large high quality roof top tent with annex (really like the CVT Denali w/ Annex) or the Wildcoast Bigsky w/ annex. We already have a mattress that fits the back of the expedition perfect, so the plan is to make that the kids bed, or at least for our 11 year old, since we have the Eddie bauer with the factory dvd player and head sets, which is an awesome way to send kids to bed and have adult time when camping.
What kind of lift exactly did you use? I'm ready to remove the running boards on our expedition as the kids are all grown now and getting in and out is easy. I really like the bumper and light bar. You've given me alot of ideas!
