Well what I got from this is that your truck is more important then your lame donation......vacation to whatever place you want to go to.
Honestly question of the day. Is this person a car person?
That being said is the truck worth it to get repair or just to sell? That is where this is going. I know ...your brain is thinking the truck is worth it but the reality might be that you should get a new vehicle because traveling from destination to destination and just by leaving it parked the parts will go in time. It is like a fancy samurai sword. You think it is a thing of beauty but the reality you have to oil the swords, maintain it's sharpness ( if used I guess ), and other parts that will need to be replaced over time, unless you keep it tucked away from heat, water, and anything else that could cause problems.
Great your vehicle needs repairs but again "how much is it worth to postpone your vacation plans?"
Why not get a rental car, or even buy some cheap vehicle with no problems and sell it back after your done with it for the same price. Again blue-book value, and anything above $2000 is not worth it.
Again your brain says " I am comfortable enough to burn the cash" but the truth is that you should be thinking " Why do I need to travel anywhere at all and what is the point of it all ? " I mean if I was with a girl I would want to fakk fakk fakkk fakkk fakk in all sorts of ways, again why travel? Your just fueling the economy that you work hard to get from which is virtually slavery if you put it down on paper.
