All of the lever guns that I have seen were 2 1/2 inch chambers. I don't know if a true top eject 94 could be converted...but you might get an idea by comparing the length of a fired 2 1/2 inch .410 shell against the length of a 30-30 case or even a 38-55 case. I have a 94 that now sports a heavy 26 inch octagon barrel in 38-55
I found out about SASS and CAS years ago at a gun show. A club that I am now a member of was set up and several were there dressed more in their cowboy dress duds more than their shooting duds. I have been set up at our local gun show for the last few years with a video of shooting playing and quite a few of the types of weaponry we use on display. It does generate some interest. I have had people ask me about clubs in the area and even had several people that had shot CAS in the past...but had moved and didn't know the area ask about clubs in the area.
Not sure what kind is on my camper. It came with the tire monitor system on it. They show tire temp and psi. However…with some of the tires a catastrophic blowout will not give you any warning. But if you pick something up in a tire…it will let you know you are losing air
