Fife RV Center Theft - Failure to return 5th wheel Tacoma Washington

On Dec 3, 2015, my 2014 41' Evergreen Bayhill 385BH fifth wheel, which was purchased brand new from Fife RV Center (Fife, WA), was released back to the dealership.  It had been impounded after the individual I had rented it to abandoned it.  After paying to get the fifth wheel out of impound, Fife RV came and picked it up on 3 Dec 2015.

I had the dealership come pick it up to perform repairs as there was some minor damage from the previous tenant.  Fife RV stated they wouldn't be able get to my fifth wheel as they were consolidating their inventory.  They closed their location in Gig Harbor and were also relocating inventory from their Bonney Lake location.  As I was living in Oregon at the time, I wasn't physically present when Fife RV came to pick up the fifth wheel from the impound lot.

I drove up a few months later, around May of 2016.  However, they still had done nothing with the rig and didn't know when they would get to it as the list of ofther units to repair was long... according to Fife RV.

Life happened and I didn't check in.  Fast forward to 14 Feb 2018 when I drove up to walk the lot and discovered my fifth wheel was no longer on the lot.  They claim it had not been moved to another lot.  Finally, I spoke with a sales manager who claims they attempted to contact me (if so, they didn't try very hard).  After not reaching me, they claim they had it impounded. 

As of today, there's no record of impound which is required to be reported.  Pierce County Auditor state they have no record of any lien which takes place when there's an impound.  Also, the credit union, whom I have it financed through, never received any notification that it was impounded. The dealership has failed to produce any record of my fifth wheel being impounded.  And they won't return my calls.

On 2/19, I attempted to file a police report, but Fife PD state it's more likely a civil matter.

I am looking for an attorney that can issue a "letter of demand" to the dealership.  When the dealership fails to produce any kind of credible documentation, a subpoena can be issued.
