30 or 50 amps?

We're working with out local dealer to order a new Jay Flight 32TSBH directly from the factory with the specific options we want. What are some opinions on upgrading to the 50amp service or saving the few hundred dollars and sticking with the 30amp?

We are sticking with a manual awning and the 13.5k AC. The trailer will be parked at a seasonal site that has both 30 and 50 connections. We really don't anticipate moving to another CG anytime in the future.

With what you state a 30 amp would be fine. However there are some advantages of the 50 amp, and that would be you can run the AC and the microwave at the same time without tripping the main circuit breaker. However, if you start to pull it around from site to site, then the 30 amp is typically more available. If you are only staying at seasonal sites, they all seem to have 50 amp services.

X2. Basically, with a 30 amp, you have one hot wire at 110V, a ground, and a neutral. With 50 amp, you have the same ground and neutral, but the 4th wire is a second 110V circuit, enabling you to run more equipment without blowing a fuse. The 50 amp is necessary if you are running two A/C units, as well. We went from a 30 amp TT to a 50 amp 5er, and were pleasantly surprised at the convenience of what the 50 amp allows us to do. For the extra few hundred dollars, I would definitely go with the 50 amps - you will remember the extra convenience long after you have forgotten the price, IMHO.

You can always dogbone with an adapter to 30 if need be.

If you have the dollars go 50 amp.

Having said that I have 30 amp set-up, run the 13.5K A/C and have had no issues running the microwave (1,000 watt) at the same time. My guess is that the only time you'd run into a problem is if you happen to be running the microwave and try to start the A/C at the same time. That A/C start load may very well trip a breaker.

Save your money. I can't see any need for 50 amp unless you plan to have two A/C units. I have 30 amp with one A/C unit and in the 14 seasons I've camped in my TT I don't recall tripping a breaker more than once or twice. When I camp, I don't do anything special- I run the A.C, the refrigerator and HWH are on electric and I use all other heavy draw electric appliances with thought. In other words, I don't put/use a toaster and electric coffee maker on the same circuit. I have a bigger problem with under voltage issues at campgrounds; especially when the demand for electricity is high. Sometimes it's serious enough to require switching the refrigerator and/of HWH over to gas. My Norcold N841 seems to be very sensitive to low voltage situations.

The 50 amp cord is very hard to roll up when it's cold. Our trailer is 50 amp and we use the 30 amp adapter and lighter cord quite often.

We have 30 Amp service on our 32BHDS. We manage OK with it, but when I buy my next trailer it WILL have 50 Amp service.

If you need 50amps the 50amps will be there, if you need 30amps the 50amp service will do that also.
Coffee maker = 1000 watts = 10amps (if it has a hot plate to keep the coffee hot)
hair dryer = 1000 watts = 10 amps
electric space heater = 1500 watts = 15 amps

All that = tripped main breaker without even talking about air conditioning or microwave.

But also consider that even with 50amp service you still need to consider power management. IOW, you can't live in an RV as though you have 200amp service like a stick house, even if you have 50 amp service.
