Not sure how a bottle jack is gonna 'tip', unless you don't chock the other wheels, or if it's still attached to the TV and you actually use the parking brake... :)
I can't count how many people I see park their vehicle, and NOT apply the parking brake... But, that's not the point of this thread.. ;)
Scissor jacks work just as well too, so choose your poison and go with it..
I have #5000 scissor jacks on all 4 corners and can and have raised one side with the rear ones... No issue at all for me.. But, I've only got a 22' TT, so if you have a 30'+ one, might not want to do that.. :)
But, the factory tow vehicle scissor jack should work just as well.
