No.

Keystone will simply point to Dometic and remind you that the fridge is
Dometic's affair.

Dometic will simply point to Keystone and, citing the vast number of their
appliances that function "flawlessly" for decades, suggest that, in the
absence of documentary proof [photographic negatives are best, slides next]
of the specific cause of the fire, Keystone's wiring must have been faulty
and that it's a Keystone issue.

Keystone will remind you that the trailer was out of warranty and, thus,
they have no further legal responsibility for the product.

Oh, yeah - they will, probably, both countersue *you* for legal expenses and
damages for defaming their perfect products.

Caveat Emptor is alive and thriving in the courts!

I think your main contact should be with Dometic.  Two years ago at an
FMCA rally in Indio, a motorhome near us caught on fire because of a
leak in the cooling system of a Norcold refrigerator.  The hydrogen
gas escaping started a fire that spread to the wood around the
refrigerator compartment, and was burning the plastic roof vent when I
saw it.  My wife took photos of the fire, the fire department came
after it was out, and the motorhome owner called Norcold about their
fire.  The owner told Norcold that we had photos of the fire damaged
areas.  The motorhome and refrigerator were both out of warranty, but
Norcold picked up all the costs of repairing the motorhome, replacing
the refrigerator with a new one, and removing all the smoke damage and
smell.  Dometic does NOT want to do a recall on any of their
refrigerators.  I'll bet that they will want your fire to "go away" as
quickly as Norcold did.
