Installing big bubble level

[dbuster]

When we bought our fifth-wheel, we also bought a large level. The sales crew said we should install the level's two metal brackets by drilling holes in the side of the trailer's hitch (I'm guessing that's actually called the king pin box) sothe level is visible from the truck cab when backing up. It's for use, primarily,in leveling the trailer side to side. The level is curved and is about 10 inches across with a 1-inch bubble tube.

Since then, I've found a sticker on the trailer's hitch that says, basically, don't even THINK about drilling holes in this thing. And that seems like pretty good advice, since holes in something that bears so much weight, even when it's made out of 3/16-inch steel, has got to weaken the whole thing.

So I'm sitting with the unopened leveland brackets, a little worried about drilling the required installation holes in the hitch to install it.

Anybody else installed one of these levels on their fifth-wheel and have any thoughts?

And, by the way, what DO you call the part of the hitch setup that is actually attached to the trailer?

I stuck the same type level on my 5th wheel hitch with good double sided tape. It works great.

I used epoxy to attach a couple of small galvanized angle bracketsto the king pin box then attached the level with 3/16 ss bolts. Almost 2 years and no problems yet.

I drilled mine 5 years ago no problems.

I drilled mine with no issues

The dealer drilled, installed, and calibrated mine during PDI when the trailer was sitting on his flat concrete shop floor. No problem.
