Given the power density of batteries and the danger of a fire in an RV, I'd never buy a cheap off-brand.
To put it in perspective:
A 100Ah 12V battery has around 1.2KWh of energy stored in it, 1 Watt-Hour has 3600 Joules of energy, so 1.2KWh has 1.2 * 1000 * 3600 = 4.3 million Joules of energy.
A hand grenade contains around 50g of TNT, at 4,000 Joules/g, that's around 200,000 joules.
So a 100Ah battery has the same energy as around 20 hand grenades. Granted, the battery is not going to release all of that energy at once, but still, a failure can do a lot of damage.
Here's what happens when you puncture one (no explosion, but an impressive jet of flame): https://www.youtube.com/watch?v=07BS6QY3wI8
