Then, the trans-fill hose between the two tanks was routed from the factory in such a way that about 15-20 gallons from the rear tank can never be used because of the high spot in the hose routing.
Another issue was the pump suction line was routed outside, exposed, along the frame instead of with all the other water lines inside the trailer where they are freeze resistant.
So we installed a new line through the inside of the trailer along side the other water lines-a rather difficult and time consuming task.
I also removed the drain valves and replaced them with threaded plugs that stay in the insulated tank bays.
When I went to work on the trans-fill hose, it split in two when I barely touched it. 😬
A new hose routed down low was installed.
I added several more layers of foil-backed bubble wrap insulation to the belly pan, and added insulation wherever I could.
Then installed some angle iron to hold the belly pan in place and seal it up since it didn’t seal properly before.
Then there were low point drain valves at the front of the trailer that needed addressing too.
First I cut them off them installed threaded plugs.
Finally, I built this insulated enclosure to protect what was left.
With that and a bunch of other work, the work trailer was ready to deploy to it’s next job.
