Were are is the main rot on the 850 ?
Replacement parts for MB are pretty inexpensive. Granted, you shouldn't necessarily have to replace parts at the 3 yr mark but I love my 1050 and plan to add the new version as soon as I can locate the XT.
Store mine uncovered in the carport and have had to replace the heat manifold due to rust. Also have have a small spot on the firebox door but not enough to worry with at the present .

The rot is everywhere inside the cooking chamber. The grates are almost ready to fall into the chamber because the little shelf at the back that supports them has corroded and only about 30% is left. I don't think I do anything wild with it for this to happen. I've used it on average twice maybe three times per month. Some months a lot more than that, some months I didn't use it at all.
The heat manifold started to rust pretty bad after 2 or 3 months of using it almost every week. Oh the excitement of a new grill :-) . The screws that hold it in place were already un-screwable at that time. I wanted to pull it out to inspect it, forget it, impossible.
At the time I didn't think much of that, but now I realize the unit isn't made to last. A pity because I love it (as you do) and the flavor from using basic charcoal is very nice.
