CObroker you are in a no win situation. Sadly, the local dealers are taking care of their own customers first, not good for you but they are forced into this since to compete with the large dealerships that sell and don't support after the sale. I can't say I totally blame them. Since we're in to prime time for RVing many are bringing them in to get ready for summer, you're in that line.
So you have a few choices;
1) Keep trying to fight Keystone, which will really get you nowhere.
2) Get in line with one of the local dealers, and probably end up with a cheap fix and not have it for Memorial Weekend (at least with water)
3) Find a mobile RV tech to fix it; either on your own dime or see if Keystone will reimburse you for the costs (doubtful)
4) Expand your dealer search and drive a bit further.
5) Call the dealer you bought it from, can you even get an appointment there?
6) Fix it yourself, assuming you know what and how to do it.*
*With some photos of what you are dealing with you might be surprised how many here can give you some advice. This isn't the first water tank issue that's been discussed over the years.
