50 amp RV outlet
I have a 240 vac 50 amp plug for a welder a previous owner had installed in my garage. I just checked the plug. I have 2 load lines a common wire and a ground wire. Is there any reason I could...

So the receptacle and how it's wired is the difference between RV friendly 50 amp 2 leg 110 and whatever RVers plug into that fries all the ac things in their unit?
What most commonly causes trouble for RVs are 30A RV outlets (which are pretty much unique to RVs; the official NEMA designation is even TT-30, where TT stands for travel trailer) wired incorrectly. A 30A RV connection is a 30A 120V connection, but the socket looks superficially similar to the 30A 240V 3 wire sockets that used to be standard for electric clothes dryers and are still in quite common use in exiting homes.
The 50A RV socket is the standard four wire 240V split phase 50A socket, as is used for electric ranges and other things. It is not unique or special, nor is it wired differently for different applications. Of course, any receptacle can be incorrectly wired and that can cause major problems, but doing so is not too likely with the 50A receptacle as it's something residential electricians do fairly frequently and it's not readily mistaken for some other part.
