1st Be aware this is not a good idea, RV Ceilings are built very light and will take much extra weight.
2nd there is no set way to do this, you will have to find the trusses in the ceiling and hang it yourself. Tioga will not offer advice on this as they will not accept any liability due to point 1.
Michelangelo's painting does not hang from the ceiling. The painting is actually painted ON the ceiling of the Sistine Chapel at the Vatican.
Down from ceiling
It's a stalactite that hangs from the ceiling.
Stalactites hang from the ceiling. Stalagmites build upwards from the floor. I found an easy way to remember which is which.. that stalactites "cling tight (-tite)" to the ceiling.
no they hang on the ceiling
The ceiling.
Stalactites hang from the ceiling of limestone caves. They form as mineral-rich water drips from the ceiling and deposits mineral formations, which over time build up into icicle-shaped structures pointing downwards. Stalagmites, on the other hand, rise from the cave floor.
You have to know the adhesive AND the ceiling construction really well to do that. I much prefer to find a joist or rafter with a studfinder, then put a hook into the wood to hang anything from a ceiling. - You wouldn't want adhesive failing and dropping something .
Stalactites are stony formations that hang from the ceilings of caves.
You get blue tack and stick it to the ceiling!!
Line Arrays
I guess anchor it from 4 separate points on the ceiling, which meet a short distance above the bag...
