Decided to black out the bumpers with Bedliner after a quick test. Rear bumper is toast anyway it’s already rotted thru in a small spot under the rear step cover. Surprisingly the hitch is good and spare pulley system is good so far. Also found my exhaust leak, nice nail sized hole in the muffler.

How you gonna fix your exhaust leak?
where's the hole in the muffler? I've seen a lot with a small drain hole about the size of the nail to let water out.

Usually that hole is under the inlet or outlet of the muffler. Drains the water from the condensation that builds up when it's started.
You will not hear an exhaust leak from those condensation holes.

I’ll grab a pic next week. Do they generally start rusting around the opening? It seemed more centered than closer to either end.

Replacing whatever needs to be replaced, unless there’s an easier way.
