Simple question about low voltage dis panel schematic?
I disconnected the charge line from the TV to the trailer because of wiring problems upon looking at the schematic I notices it says Hoist what would that mean?

Please give a bit more information as to what your question is. Your attachment was for a 3M fire stop. What does that have to do with your question?

A researched WAG
The schematic might be referring to power for the tongue jack.
My clue comes from this post.

Not sure what problem you are chasing down but the M terminal goes to the trailer battery. The S terminal feeds the jack with current flowing from the battery to the jack. The T terminal is the feed from the TV to the trailer battery with current flowing to the battery from the TV while driving.
It is strange that the fuse at M is 50 amp when the fuse to the jack is only 30 amp. The engineer at Airstream never took DC electric 101.
What problem are you troubled by?

What is the basis for your statement?

Without actually tracing each wire I have to go by the schematic. M is battery positive which would be necessary to feed the "Hoist" jack and is generally a 20 amp fuse. T would be the charge line coming from the TV to the positive terminal of the battery and is generally a 30 amp line.
The oddity of the fact that they use a 50 amp fuse in line with the other 2 fuses when the possible current flowing in either direction through that fuse can not exceed 30 amps. This would be if the trailer batteries were dead and you were running the trailer completely off the TV. If that load exceeded 30 amps, which is highly unlikely, the 30 amp fuse would blow first.

Ok I beleive it is the "hoist" jack and it is 20 amp fuse so that should be for the electric jack... I am not thinking I was thinking it was Host not hoist da...

If you find one marked "hoist by your own petard", pull the fuse!
