Similar thing to both our 3/4 ton and our 2 ton. Mice had filled that panel with relocated seat filler as well as the doors. We salvaged the 2 ton's but the 3/4 ton's was rusted right through and the nuts are solid. We cleaned the whole cab right out and the mice still like it! All there is left is the
cab I can't figure what is so special there for them now...
