Keep the truck. It's not about a payback for all the abuse from each of your family members. It's about you getting something deserved, it's about something finally being somewhat in your favor, even though it really isn't even that fair to begin with seeing as your brother gets everything he wants and is getting the better deal out of the inheritance. If you haven't spoken to your brother about why you should get the truck I would definitely take the time to do so. If he refuses to see where you're coming from then don't sweat it. This whole situation seems to be in line with how things have gone for you your whole life, so why feel bad about taking something for yourself when it hurts no one? He doesn't try to better himself by getting a job or selling the motorcycle to buy a car, how would you giving the truck to him solve anything? I would take it, and if you don't then take comfort in knowing that this could be the last thing that he will ever be able to take away from you by being a whiny brat child.
