Oil Changes and Overheating- A Cautionary Tale

Thats a bummer, and thanks for the heads-up, but I have to add something; the oil fill issue belongs to the builder of your MH, not the chassis. Back when we had our gasser I did all my own changes as well - filling it was never an issue.

The chassis builder has no idea what the house builder does with it after it leaves the factory.

On a side note, I'm thinking you may be able to recover some of your $$$ by selling your perfectly good, now clean, spare radiator on eBay.
