....I agree that a steel liner would be a benefit but there are several pitfalls. Water will get behind the steel and cause rot problems above it. If there is much room, it could be spaced away from the floor so it can dry. The edges, and especially the ends, would need to be anchored so that a failing tire cannot grab it and cause even bigger problems.Galvanized steel is available and that should last longer than the poorly painted frame.
I wasn't under any type of warranty with my blow out and destroyed sewage bay. WHICH is enclosed EXCEPT for the side where the tire is. :R
They wanted $2,000 to repair the damage. I did it myself for about 100 dollars in parts and screws, bolts and the turnbuckles.
I used a steel 'grate' material on my fix which allows water to go thru.
