I winterized my rig on the weekend, no problems but I noticed the hinge on the water pump door was held on with double sided tape. There was one screw holding the hinge to the frame and none holding the door itself, I spilled some antifreeze on it and it fell right off. Crazy, it took me about two minutes to put the missing three screws in.
I found some Dynamat Extreme on sale and applied it to the motor cover over top of the factory insulation and then covered that with Dynaliner foam. Hopefully it will help quieten things down a bit. The motor cover didn't use as much Dynamat as I thought and I should have enough left over to do the door panels when I replace those door speakers
I picked up an Air Lift Wireless One for the airbags, it's a lot smaller than I thought should be no problem to put in either of the side compartments but probably won't get to it till next spring.
