repair it?? my tractor (truck) was involved on a accident. It will be a total loss. I will get $22K and keep the vehicle but I still owe $25K.... I bought the vehicle from the insurance for $6K!

The adjuster estimated all parts brand new from the delearship, but I can get them used for much less and I have my own mechanics and cheaper labor for a body repair.

Can I just continue making the payments to the bank, fix the truck with $10K and pay the remaining $12K to the loan??

I called the bank and they told me I can continue just making the payments like anything happend, but if they own the truck and Im still paying for it, they shouldnt be concerned about that??
Yes, the vehicle is a total loss, and it can fix for much less. There's no mechanic problems. Actually, the driver after having the accident, drove back home and the truck works perfectly ok, there's only damaged to the hood, one side, and other side, not big deal.

I live in the border, so I can take to Mexico for a cheaper labor and buy used parts.

I will get $22K from the bank and the truck, and fixing it will be not more than $5K.
OK. One extra comment:

If the vehicle needs to be retitled with a Salvage Title, that's gonna be after the vehicle is fully paid-off?? Or the bank will still have the original title like anything happened during the remaining loan term and file a new salvage title after that??

Usally if there is a lienholder on the veh the insurance company cant make pmt directly to the insured alone. The lienholder usally needs to be added. Now if you bought it back, and can fix it vs. totalling it out then go for it. The bank only cares about getting there money. Its not very often that a veh gets totaled, and can be fixed, and still have money left to pay on loan..

When a vehicle is insurance destroyed, if you owe more than the value of vehicle, you are responsible for the balance owed. This would seem to be your situation, but you also want to retain the truck, which you are able to do. Now, as for the title, once the truck is repaired, it must be inspected by law enforcement, and declared to be roadworthy. They will want proof of parts used, receipts for all parts/labor. Once the inspection is complete, you have to have the truck retitled, as a salvage/rebuilt, and the lender will need to be a part of the process, as they hold the current valid title. When you pay off your loan, the title you receive will be branded salvage/rebuilt, and can never be a clean title again. As long as you make your payments and carry your insurance, your lender will be happy to work with you.
