Instead of wiring my flashers I am looking at adding amber strobes with a separate switch http://shop.advanceautoparts.com/p/alpena-twinstrobe-amber-77234w/10461231-P?zoneAssigned=1&prefZC=29445
I ran into a really bad pop up storm with almost no visibility and if that ever happens again I want to be seen. I talked to local law enforcement and the State Police and they said it sounded like a good idea.
Other than normal tune up items there is an upgraded Ignition you can purchase I think Freebird had one on his 99 and you can also put in a new cam, however the advice Jeff gave above is probably really all you need.
Thanks for the post my shock went out coming back from MD so this comes in handy. Mine is still holding air and no signs of leaking but bounces like a pogo stick on bumps.
