I have a 2000 F-250 Crew Cab with cap with the 7.3 diesel that we mostly use to drive all our stuff 800 miles oneway to Bullfrog on Lake Powell, also to tow our boat once in a while. The problem is that our Lariat version of this chassis is leaving me wornout at the end of the day. Just too damn noisy for a 12+ hour day! Is an Excursion any quieter? It is mostly tire roar and wind noise, plus the diesel clatter. I have Michelin MS tires, not aggressive at all, and all the door and window seals are either in good shape or new. We need something big since the back seats are removed for our dogs and we fill the back of the truck with genset, gear, fuel, propane, and three Yeti coolers. No way would an Expedition or Suburban work for us.
