Just remember that they are not immune from leaks I bought a Scottsman TT and it had major water damage from a leaking Atwood water heater I got the trailer to get the axles and frame so the rest didn't matter. The Water heater had several pinholes in it and was trash. Cause of leaks were possibly due to owner using steel pipe fittings on it. As you know that is why Atwood uses a plastic drain plugs and fittings.
