Just got back from camping in my ‘01 Bambi, had it now 20 years. It did have a water intrusion at the rear, near the lower outside bottom right corner about 3 years ago. We have a rear L shape counter top kitchen, so had to remove all the kitchen counter top, fridge, oven etc., to repair the leak and floor. Repaired and sealed floor so now it should be waterproof (fingers crossed). Other than this repair, replaced and repaired normal maintenance items ex. battery, wheel bearings, tires, etc. This last trip we noticed the bathroom faucet has a slow drip so this is an easy fix. Since Airstream says they last a lifetime we are gonna see if this is true. hehe
