Always fine to remove interior sheet metal, clean, re-insulate, whatever.
But...I was advised years ago by a retired Blue Bird engineer that it should go back in. The nature of the shell design on nearly all metal bodied buses relies on the box beam effect created by the two separate skins attached to the ribs inside & out. And no...this is not just for "roll over" protection...it was described to me as basic to the original design's structural integrity.

OK..I said it (again). Jump all over it. Or...ask a qualified structural engineer to compare the two design options.

I opted to keep both skins on my old 40' Bird and on the little Wayne I am working on now. Everyone here is also free to make whatever choice suits their fancy as well. I am not saying that my choice is the only "right" one, just passing on what I considered to be information worth considering from a reliable source. What I am proposing is that you try to get as much qualified info as possible to base your choices on. Especially as regards the fundamental structure.
I agree with this...and the gremlins.

We have rolled full size 66 passenger buses down a hill with the excavator when cleaning up a spot for the crusher.

Two out of 5 had no interior panels. However, the two without didn't deform any more than the three that still had the interior panels.

A few dents, and none of the 5 where still square inside. That was the extent of the damage.

That's what I based my dissension on.

Alright so what it sounds like from what I've read here and on other sites is that the interior skins were designed to help reinforce the bus and make it stronger, but they aren't vital. A lot of people have removed the skins and experienced no problems as long as they make nice with the gremlins.

What would make you feel better- mold and funk hidden in your hot or cold (depending on the weather) metal interior walls, or .0000000000000001% less crash worthiness?
Sounds like you're playing it smart... asking questions FIRST! just weigh all your options and consider it all and then make an informed personal decision.

I hate buses getting crushed. They crushed just over 100 when I first stared working for them.

It feels like a waste of good parts.

So my dad is still upset about this. He said that the outside rivets will loosen more quickly without the interior skins. Did anyone experience that?

I drive down some crappy roads and haven't noticed and rivets loosening. They're totally unrelated.
Just speaking from my personal experience but skoolies and parental approval RARELY go hand in hand in any regard.

Show your dad this site.

Show him the input of all the people with Real bus experience. Not just a Opinion.

There are far to many of us here that have removed the interior skin with no negative effects.

I love my father-in-law, and when I bought the bus we were working on it together a lot. But I quit working on it with him a while ago. He's got a lot of opinions and they're slowing me down. People on this forum have opinions too. Don't let them slow you down either.
