I bought a Handi in .30-30 about a dozen years ago, ostensibly for my (then) kindergarten-aged son (who's a "Southpaw"). In the meantime, I enjoyed the little rifle myself (of course) , which shot into about an inch with either flavor Remington factory loads and handled like a dream in close quarters.
When my son became old enough to hunt, I ordered a "youth" buttstock for the Handi and set it up for kids. The boy has graduated to an adult sized Marlin 336 (also in .30-30) and the Handi now serves new kids each year in Michigan's Youth Hunt (a September weekend for taking whitetails). I sat beside another youngster a few weeks ago who took his first deer with that rifle. As usual, the 150 gr. Corelokt zipped right through the forkhorn, and no tracking was required. Perfection!
I understand why you'd choose the .30-30 Handi for a stowaway in your RV. It's very accurate, sufficiently powerful, hardy, "handy" (of course!), ammo is ubiquitous and it stows in a tiny package. It can feed you, protect you and entertain you for pennies. What's not to like?
