After doing considerable research and minus any help from Lippert in spite of 2 emails to their customer service, I have found Field Repair fittings for the hose in our Montana's.
The fittings are from Parker and will likely not be available just anywhere but should be able to be ordered from any decent hydraulic repair facility.
The hose end Parker number is: 20651-4-4 This can be used to repair a leak near a fitting.
The adapter fitting Parker number is: 9393-4-4 This could be used where a hose might break or be leaking anywhere along the hose by using two of the hose ends and this joining adapter.
All that is needed is a couple of wrenches and something to cut the hose cleanly where the new fitting will go on.
Here is a picture of 4 hose ends and 2 adapters I will now be carrying with me wherever I go in the Montana.
