As previously mentioned, we went to NIRVC in DC for our annual servicing of the engine, generator, Aqua-Hot, etc.

They used synchronized jacks to raise up our coach:

They pointed out that the oil pan has a bit of a leak, but we decided to not doing anything about that this time; we’ll keep an eye on it:

They also indicated a leak in the radiator fan, which we did address by replacing it (a rather expensive operation):

The bar between the front jacks was loose; the bolts on one side were broken, so they fixed that:

They also replaced the engine air filter, as we do every year:

And serviced the Aqua-Hot:

We usually get various branches of NIRVC to do the servicing, for consistency.
