Attention: TDR Forum Junkies 
We bought our Ram 2500 quad cab 4x4 new in July 2004, right after getting it home I started my new truck inspection. You know looking for things like wire chafing and lose bolts. It was then I noticed it, the A/C Evap. drain was set to dump a stream of water right down on top of my frame and suspension link bushings. As you know this will cause the rubber bushings to dry rot and the frame to rust. I expect to own this rig a long time and as such have obsessively taken care of it thru its now 140,000 miles.
This post is to walk you thru a $15 fix I applied the first week I owned the truck.
I measured the OD of the A/C drain at 3/4 in. and went down to the local auto supply looking for a long heater hose with a 90 deg. bend very close to one end, other wise it needed to be straight with a 3/4 in. ID. We went back to the hoses hanging from a rack and right in the middle, there it was. The clerk said he thought it was a Chevy heater hose but that he wasn’t sure. I have included a photo of the Part number on the hose. Its 4 feet long or so, long enough to route from the drain back outside the frame to a point between two passenger side doors. I secured it to the drain with a hose clamp and routed it down between floor of the cab and frame. Then between the frame and cab mount securing it with large zip ties. That was 5 years ago and today it is still working perfectly.
I have seen some other trucks of the same vintage as mine and noted the rust and dry rot is a real issue on a couple of them. I hope this helps some readers avoid what could be a very expensive repair later by spending less than $20 bucks and 20 minutes today.
I sincerely hope this helps, its worked great for me.
By the way, the date on my camera is a little fast. Guess I need to set that tonight.
