All your choices make me nervous. Each in their own individual way. I would try to score a Benjamin Akela in .22. The selection of truck guns gets better when you’re willing to beat up a $1k+ gun. But I understand where you’re coming from. If Kral was still around, they made good truck guns. Remember, big temperature swings don’t mess with an unregulated gun. They also have less things that can leak.I have a fx maverick for slugs so this gun will primarly be pellets
