30A inlet so cheap, how?

IMHO, if it seems impossible it probably is, and remember the old adage, "you get what you pay for". Personally I have seen the Furrion name the most and held their products in hand. They seem highest quality of most that I have seen anywhere. When is comes to something that requires as much attention to safety as electrical systems do, I'm all for spending a little more and installing that quality in the first place rather than taking risks over a couple bucks.

That's a TWIST LOCK. Good luck finding an RV cord that plugs into an RV park receptacle. Twist locks are for construction workers and boats. Plus it's plastic. It will probably melt when  it gets a little warm. Don't cheap out on electrical. It can cost you your trailer or your life.

Am I missing something here or not understanding your comment, Larry?

I have used twist lock 30amp cords on all of my teardrop builds, as well as, all of the restorations/rebuilds on vintage trailers. Never had one get the slightest bit warm. Here on the east coast, never had a problem using the twist lock cords on the RV park power boxes.

As long as the Park Power end of the cord is the normal RV two blades and a stub for the RV Park receptacles it's OK. I just don't know if I would want to use a cheap $10 inlet for my trailer. I guess they would be OK. I'd have to inspect it in person though. But all the RV parks I have been to don't allow for a twist lock at their end. The trailer end doesn't matter what you use.

I bought the Furion inlet from VTS and when I found out they didn't sell the cords any longer I had to go hunting. I found one and it of course had the twist lock with locking ring at the trailer end. What I did not know was that the other end was twist lock as well which won't work in an RV park. That was for boats. So I had to send it back and pay about $45 in shipping. The cord was only like $65.
