As part of the clearing out of the old A/C components from the cavity where the new tank will go, you also need to make a passage for the new water lines to get to the tank. I found this conspicuous looking sheet metal plate tacked on the main cross-member and discovered that sure enough - this is the passage that was used on the early coaches to get water to & from the lower forward tank. It's a bitch to reach and get opened up so jack the coach high to make it some easier. |
You'll have some cutting and grinding to do to get this prepped for the tank. |
Be certain to get all hoses & wiring up and out of the way of both the tank and the steering rack! |
Install done. The last part went better than the beginning. With the exception of not being able to use the fiberglass housing top-cover (because I made the tank 1/2" too tall) it all went the way I wanted. The tank is still insulated on top regardless. Here you can see the pathway to the round hole in the cross member for the water lines and the drain ball-valve etc. The bottom sheet metal original cover served well to hold the tank up. I added a 1"x1" cross bar as well for extra support. |
