It looks like I might be answering my own question this weekend.
While just poking around under our rig this evening, checking out a section where the dealer or factory made a repair to the underbelly. I found some red fluid leaking out of the repair area. Draw your own conclusions as to why there was a hole cut previously and there is now hydraulic fluid leaking out of a brand new rig. The dealer made the repair by using silver foil tape and black silicone. Well that plan didn't work, might have had something to do with the fluid running all over the place.
Well, being stubborn and not trusting the dealer, I am going to pull the underbelly down and see where the leak is.
My plan is not to butcher the underbelly. I am going to simply drill out the teks the factory installed. Hopefully they are soft enough to drill. They have all been cut off with an abrasive wheel, which is going to make drilling them out easier, and hopefully it softened them up a bit. Then I will pull it all down and have a look see, and clean off all the fluid. I hope to be able to replace the underbelly by bolting it back down. I plan to send a 1/4" bolt with a fender washer or two back into the same holes from above so the nut will be exposed below the frame. On our rig the underbelly and foil stuff just sits on the lower web of the I beam frame. And It appears the underbelly is flexible enough to get the bolts in from the top.
Anybody thinking I'm nuts? I'd be happy to hear your opinion. I have already fixed a hundred little things that the factory/dealer missed. You know those little things you dint notice until you've spent a few weeks in your rig. And I'm the kinda guy thats not taking it back to the dealer unless the sides fall off, so the obvious reply of I'd take it back to the dealer is a valid opinion but not necessarily mine.
Any suggestions are welcome
