As an avid Jeep Cherokee and Wrangler fan I always had a great respect and like for the Suburban. I use my 99 Xj to plow, pull my fishing boat and pop up camper and haul my family during inclement weather. Up until June it was fine for my needs. That is until my new Daughter was born. My other Daughter was 11 at the time so there was still plenty of room for all of us up until this point. I have a lift, lockers and recovery points on it as I do drive off road at least 25 times a year and live in the middle of nowhere. The Jeep will still remain my plow and off road vehicle. I'm just saying hi and enjoying the wealth of knowledge for the Suburban. I do not own one yet but the hospital bills should be done soon and I will be buying a Suburban. I plan on buying a 2000-2006 Suburban with the 5.3l and 4wd. Kind of wanting the middle bench seat instead of captains chairs. I figured the 1/2 ton was the way to go as I do 90% highway driving and 19-20 mpg would be nice as I hear the 6.0l gets only 17 hwy. I will use this vehicle for towing, and hauling family. Been steering away from the Yukon XL with full time AWD. Is it a more of a gas hog? I see brakes are a good upgrade on these. Is there a rear disk conversion? Is the programmer worth the cash? Anything to watch for as trouble areas? I do all my own work from engine swaps to mild fabrication so I'm not scared to do some wrenching if it's worth it. I look for MPG, safety, comfort, and reliability as the main goals for upgrades. Of course not in that order.
