Its true that Hellfire can give alot of trouble I've seen that first hand, but can give good results too. Also that the muggy has got its own issues like clutch problems. Its not funny buying a truck and before you even used it you have to change the clutch system.
Personally for all the choices we have out there and at varouis prices I wouldnt choose any of the above but I would go for something less problematic. YOUR CHOICE
