would this be OK to stick my satellite dish to the top of my motor-home without screws?

It's a good product but I would not trust it for that, use it along with the screws, just to be on the safe side. Is there not a plate with the dish that you could fix on permanently so that you could easily remove the dish?

Dear, May i know the best before date?

Morning. Exp Date of current stock is 09/2023. Hope that helps.

Can I use this to seal a roof vent on my camper? I need to make sure it is completely watertight. Thank you

Yes , you can , and it will seal against water ingress, It's also used for sealing deck fittings on a yacht or seagoing motor cruiser.

Would this work for waterproofing cracks in outside concrete steps

Probably would, but I would try concrete first of all to fill the gaps, it would look better.
