Where to buy a 30A plug inlet

www.walmart.com/ip/RV-Designer-S971-30-Amp-Flush-Receptacle/44126750



Walmart.com is cheaper

Would this one be fine for me??

Also does anyone have a source for not so expensive cord to go with it?
something like this is what Im talking about www.amazon.com/Camco-55501-PowerGrip-Standard-Locking/dp/B005BNZGCS/ref=pd_sim_469_1?ie=UTF8&psc=1&refRID=36J8MD500J8FD1906ECJ

Anything else I need to go with these?

The link to the Amazon $33 inlet is fine. I wouldn't buy the cord tho. Go with an adapter and add a regular RV 30 amp cord. Reason being, the 30 amp cord will work for a lot of things without having the round "special" end on it. Adapters are reasonable and available almost everywhere.

The Flush receptacle from Walmart is designed to fit an electrical box; it's the one the above cord plugs into.

This is the one I bought. Not cheap but the quality is good.

The cord can cost a lot. I bought this one. Not the best, but very good.

You could always wire for 30 amp now and go with a lighter inlet if you don't plan on having a heavy power need.

I think vikx may have meant to cut the female end off....the plug will then connect your breaker or junction directly to the campground box. This is the setup my 16SC has, the only difference in the design is having a space to push the cord inside, under the dinette or some other closed space.
