30A or 50A Choice

this is what I was wondering, can you can plug into a 50 amp supply with a 30amp R/V with a proper adapter? and if so can you draw 50 amp. I guess what i'm try to get to is the cord from the R/V to the power supply on a 30amp R/V is not rated for 50amps. mine looks like # 10.

If you plug your 30 amp capable RV into a 50 amp source with the proper adapter, you'll only be able to draw a total of 30 amps before the RV's main breaker trips. Only a short in the RV cord itself could draw a heavier load, but the 10GA wires in the cord are capable of tripping a 50 amp breaker if shorted. A partial short could conceivably cause enough heat to melt the insulation before the breaker trips, but that would be an extremely unusual event.

Which would you choose ?

Before posting read your own words. Ask your self would "I" be able to answer my own question with the info "I" provided???

What was the OP actually asking? Was a pretty open ended question.

Since you are in Texas, as I am, I would recommend an RV with 50 amp and two A/Cs.

X2^^. In addition, what a lot of folks don't understand is that 50 amp service isn't just 50 amp service. It's two legs/phases of 50 amp service capable of supplying 100 amps total to your RV. There's a HUGE difference between that and single-phase 30 amp service.

Here's some food for thought. We have a 5th wheel with a 50 amp system. When we tried to make reservations at a KOA near Pittsburgh last summer, we were denied because they only had 30 Amp sites left when we were going to be in the Pittsburgh area. Even though we don't have a washer/dryer or a second air conditioner so there would be no extra draw than what a 30 Amp camper would pull, our camper is wired in case we were to add those things. We have a 30 Amp to 50 Amp dogbone to make the pedestal connection when necessary and explained all this to the campground owners, but they still would not let us book a site. From what I've been told, many KOA campgrounds are going to this policy and other campgrounds will likely follow this business model in the future.

One reason I was interested in this post, was that I had just inquired about a camp site. I asked if I could have a 50 amp site, my T/T is 30amp. I was told I could only have a 30amp site for my 30 amp T/T.

What if I have 30 RV and only thing left is a 50 space? Will they let me crowd out the big shiny class A that needs 50?

I think they would be happy to know you paid for a 50 Amp site and can't use that much juice.

Depends on your expected power usage.

If you're buying a fifth wheel or trailer go for the Fifty amp. Should be all that is installed in MH.
Our Fifth Wheel was 50 amp with only one ac but provision for a second ac and a generator.
Depending on hwo well the rv is insulated a single ac is not likely to be enough in Fla or Southwest, especially when it hits 110 degrees or more.
our mh will run both aac's on 30amp but not much else and not at all campgrounds depending on voltage etc.. You can always use a 30 amp pigtail on a 30 amp service but not a fifty amp adapter on 30 amp service.
With tv,heat pump(s) water heater, lights and convection/microwave oven or other things30 amp is just not enough. Some people use small heaters in colder climate and 30 amp is just not enough with anything else or by itself.
You can make do of course with 30 amp but why?

I was quite surprised when a friend who has only been RVing for a few years told me a campground she stopped at ONLY had 50A service. So of course, she paid the camp store price for the 50A/30A "dog bone" !
