Our RV tech also along with the other changes the converter would also need changing????

We ran another breaker box and now have two 30A pigtails / cords the second ran to a 50A to 30A adaptor for the pedestal the 30A beaker box will protect the trailer.

You would be OK if you replace the 30A socket on the camper with a 50A plug, continue to run to the existing converter off one leg and wire the second leg to a new 50A panel with appropriately sized wire. DO NOT change the 30A breaker in the existing converter to 50A... the existing wiring from the socket to that converter is only sized for 30A as is the bus inside the converter - you will melt/burn something. You could then move some circuits from your existing 30A panel to the new panel to balance the loads.

what suggestion was that? nobody said anything about what gauge wire, just that they would runa leg. 50 amp, 8 ga and 30 gets 10ga.

Crokett I missed your first post. I was on my phone scrolling with my thumb. I will agree with your first post 100 percent. I was referring to the licking of the fingers (I think he is joking) and 8 gauge 3 wire. Not the right number of conductors which would leave me to believe there would be some kind of rigging going on. I should have worded my first sentence differently.

The only reason I suggested the adapter is if 1. The 50a outlets tend to be less abused at campsites and 2. No changes to the current loads on the TT. Scotty said he saw trailers with prewired for the second ac not that he was going to add one

why would you buy a new camper that you already knew doens't meet your demands or needs? You can get 50 amp as an option in most campers these days. Should have just looked harder or ordered one.

its all good...thought maybe said something dead wrong ..pardon the pun. a lot of coaches ( 27' and up) are built with one AC. these may cool inadequately in quite a few areas of the US. some people may not want to step up to a coach with 50 amp service. a second AC would be a pretty common upgrade IMO...

No all is cool. Thanks all for the comments. Was just wondering what was involved and I'm no electrician. Not looking to install a second AC. Wife is just used to running Hair dryer while AC is on etc (in our 5er). She ask so I ask. No problem. 30 AMP it shall be...... We love this unit and out previous units were all 30 Amp.

The reason I'd consider going from 30A to 50A is not to add a second A/C. When our single A/C is running and the microwave is running, either the trailer's 30A breaker will trip or the park's 30A will trip. With the plug converter, it works most of the time but if the water heater starts or a hair dryer is used, the trailer breaker will trip. I've considered unhooking the A/C circuit from the panel, adding a single circuit breaker box and supplying power through a # 12 extension cord and plugging it into the park's 20A outlet.

Issue with 50A to 30A dogbone adapter

Risk of fire. The danger is between the 50A breaker at the campground panel and the 30A breaker in the RV. In other words, the 30A cord and where it makes the transition from cord to the RV's 30A hard wire that goes to the RV's breaker panel. I have repaired an RV where the 30A cord/hard wire transition (in a metal junction box) burned up all of the wiring inside the junction box. If it wasn't for the metal junction box, it would likely have burned up the RV instead. Everything between the campground panel and the RV's breaker panel (internal RV wiring and cord) is designed to carry 30A - and you will be plugging it into a 50A breaker. Ask any electrician about attaching a 30A cord to a 50A breaker.
