What to do with my truck

Put this in the off topic discussion because of its random nature. Trying to weigh options here and figured I'd express them on the forum so that I can gather opinions and think out loud.

I have a 2017 tacoma and a sprinter van I've been converting for a while now. The sprinter is finally ready to go and I'm wanting to start a trip with an indefinite timeline. My work is remote, my friends are renting my house, and I can easily store the truck there. Financially I can cover the remaining payments I have, and I am net positive due to the holding value these trucks have.

My father has expressed interest in a new car, and he and my mom are looking to get into RV-ing. Ideally their goal is to get an SUV and tow a larger trailer, however they would like to start with a pop-up/tear drop and get a feel for towing. Recently over dinner we had a brief discussion of things with the possibility of taking over payments while I'm gone.

At this point I feel that I have 4 options; Sell the truck someone else, sell the truck to my parents, have my parents take over payments, hold on and pay for it myself.

I don't thing I'm ready to let go of the truck to someone else at this point, as I don't know if van life is going to be a definitive future; plus the van is only 2wd and I'd like to have a 4wd capable truck.

The only benefit I see in selling the truck to my parents is lowering payments by spreading over term, which might not be beneficial due to the interest rate. I don't need the cash at this point, so theoretically my best two options are hold it or let them cover the current payments. Either way it is a depreciating asset (liability) if I let it sit at my house or let them drive it. If I were to come home for a period of time I'd also be able to share it with them as my father works remote as well.

What are opinions on pros and cons? How should I handle it for future take back or sale?
