Q: Worth saving

I have a dump truck I need to know if it's worth saving. The dump bed has a lot of rust can it be welded? Also the right rear dual is leaking after changing the rotors, abs system is leaking, the gas and speed gauges are not working, the wiring needs checked works sometimes and sometimes it doesn't and needs a new front bumper
