Welcome to the forum. Make friends with that search bar on here... you're motor is no different than the MM or the Ram50, despite its badges, and even though its the more rare, you'll get a lot of information here.
Pennyman's profile should be your bible should you choose to do any repairs or modifications. Geronimo is a beautiful truck and his Pennyman's knowledge is impressive. Several of us hold these 1st gen gems near to our heart and happily welcome another to our community.
Let us know if there's any questions we can answer for you.

P.S. One of our members and moderators (Brad) lives near Tacoma. He'll be happy to hear a neighbor truck has found its way to the northern streets!
