IMHO truck guns fall into John Tappin's perfect packing pistols and as such there is no one correct answer. The quest will lead you to a collection of guns that bounce around a general versatility aspect one is always a little more capable in one aspect and deficient in another. Still a combo gun works well in this aspect I have a older 24 in 22mag/20g that I really like in the role.
A 357 lever also works well and I can tell you from experience a 38 special lead round nose or FMJ/ball ammo isn't any harder on cottontails than a HV 22 hollow point.
