We just bought a used Coach House Class C motorhome and the 30 amp plug configuration (see pic) is the same as a boat shore power cord, but I have seen a different configuration where the ground prong is round rather than "L" shaped. Do campgrounds typically support both types or do I need some type of adapter to use either type??

You will need an adaptor. Something like this will work.

They also sell power cords with the 2 ends you need already on them.

What is that actually a picture of? Your shore power cable? Does it have the same pin configurations on both ends?

It's not uncommon for an RV to have that sort of connector on the side of the RV, and a shore power cord that has that on one end and the other kind (two flat pins, one round pin) on the other. The two flat/one round is what you plug into at a campground.

As FlyingDiver as stated, typically your pictured connector mates with a female connector on the outside of your RV. That connector then goes to your shore cable with a standard ANSI C73.13, TT-30P (plug) on the campground end. All campgrounds have a matching TT-30R outlet if they provide 30amp Service.

Thanks, Twinboat that adapter is just what I need. Greg

Picture is my shore power cable that I borrowed from my boat. The picture shows the end that connects to RV and other end is the same pattern that plugs into campground... NOT!. It turns out boat shore power cables are different than RV shore power cables. I learned here that RV plugs have a round ground prong while boats have a flat one with the L shape. I did find an adapter that goes from L shaped ground to round shaped ground so I should be able to use my boat cable.

Where is the shore power cord for the RV?

Don't have one?

Might as well buy an RV twist lock 30A RV Power cord vs boat/rv adapter
Then Boat has its own and RV has its own power cords that STAY with boat/RV

He may have acquired a few spare marine 30 amp cords over the years. I think I have 6.

I have adaptors to use them as extensions on the RV and have installed the 30amp twist lock outlet in all of my family's homes. They fit in a standard outdoor box with cover and lock in. No confusion about dryer plugs either.

Yes. It is an extra spare for the boat and is 50ft long. The one that came with RV is only 30ft so for the cost of an adapter I have a 20ft longer cord. I also installed a "twist lock" 30 amp outlet in my garage so I can plug in directly at home. Good idea to adapt the boat cord to the rv cord as an extension.
