Ok, so you bought the rig on eBay. IMO, first issue. Transfer of vehicle was under a confrontational environment.. second issue. You didn't review the title prior to leaving.. third issue. The 40 was bought by 2 other people that never paid taxes or titled it.. fourth issue. You've put an insane amount of money into the rig (looks great BTW) without being the rightful titled owner..fifth issue. Lots of issues with this rig..
Have you called your DMV to discuss this issue and what they recommend from an anonymous standpoint? Or are you worried that all your work/money will be jerked out from under you...(I know I would be)
My view on the matter... The "Original" PO is NOT the owner of that vehicle anymore, (whether his name is on your title or not) he legally sold it. Ethically he has no right to apply for a lost or duplicate title. Have you run the title to verify it is still in his name? Scandalous people in the world today. For all you know "your" 40 could be tied up in a personal loan lawsuit/larsony case and the reason it hasn't been repossessed is because they have no idea where it is.
Little story...I had a buddy years ago that sold a titled piece of equipment to a guy who never titled it... The new owner took out a personal loan with someone, used the equipment for collateral and then sold the equipment without paying off the note. Long story short, my buddy spend over 10k in lawyer representation fees and he did what he was legally required to do by law. They found the piece of equipment and gave it to the plaintiff for settlement. The man that the equipment was seized from was fined for not properly titling the equipment and lost all monies paid for the equipment.
Not saying this is what is going on here, BUT DAMN!! WHAT IF!!
I wouldn't touch this with a 10' pole. I feel the guy you are asking for help is a stand up fella and I respect him for his position. You say he's a vendor here, PM me his name, sounds like a guy I'd like to do business with. It's the people that bend and don't follow the rules that screw it up for so many others...
I'm with Tucker, apply for a bonded title and wait out your time.
