30A or 50A — how do I know which EMS I need?
Look at your RV's shore-power cord. A 30-amp rig has a TT-30 plug (three prongs); a 50-amp rig has a 14-50 (four prongs). They aren't interchangeable, which is why the EMS is a single-buy pick-your-rig choice and not in the add-all cart.
Do I really need an EMS, or is a cheap surge protector enough?
A $30 surge protector only catches voltage spikes. A true EMS also detects miswired pedestals — open ground or neutral, reverse polarity — and high/low voltage, and disconnects automatically. Those wiring faults are what actually destroy RV electronics, and a surge strip won't see them.
Why aren't power adapters / dogbones in this pack?
Because they're amperage-specific — a 50A dogbone is useless on a 30A rig. We keep the bundle rig-agnostic and put the full dogbone matrix (30↔50↔15A) and shore-power-by-region reference in the companion guide so you pick the right one for your rig.
I'm renting the RV — is this pack still for me?
Especially. Rentals come with the rig and basically zero hookup gear. This is the water, waste, leveling and tire-safety kit renters end up scrambling for at the first campground — minus the rig-specific electrical, which the guide covers.
Does 'Add all to cart' include the EMS?
No. The add-all button loads the rig-agnostic core — water, waste, leveling and tire safety. The EMS is single-buy so you choose the right amperage for your rig (30A or 50A).
