Airstream Bambi Sport 22FB purchased new and we are the only owners. We own outright and have the pink slip in hand. When we purchased we upgraded and added through the dealer the following: shower door, statinless steel gravel guards, rear bumper with storage and hitch receiver, dual batteries, and weight distribution hitch. Since we have had the trailer we upgraded the 12v electrical to two 6v golf cart batteries with a new charging system that has a 4-stage charger vs the single stage that came installed. The electrical system also has a power use monitor installed as well.We removed the Formica kitchen counter and replaced with a quartz counter. We removed the 2-basin sink and replaced with a single large basin and new faucet. The TV was upgraded in brand and slightly larger in size. We have added a power tongue jack and an additional sewer hose storage. The speakers have been upgraded and We added a cooling fan and vents to the stereo DVD player box to keep air movement around this system. We added a drawer system to the wardrobe area to allow drawers for clothing. Brand new water pump. We upgraded the propane to be 33% more and added stainless lines with gauges. We installed a OEM 2” lift to make it easier to tow and not drag the rear end. Custom bike rack with generator off of rear bumper, tongue based storage shelf, teak shower grate, Lastly, the weight distribution was upgraded to a new system that is much easier to apply and keeps the trailer very stable while towing.We have cared for as is if it was our forever trailer. We are only selling because we are getting a slightly bigger one.there really is no to do list and there are no issues. The gvwr is 4500 lbs and the tongue list as 400lbs.
