How much is the $$$$ for the upgrade to 50A? Unless its a big number, go with your gut. I wouldn't consider it but then I use my TT in a more conventional manner. If you plan to set up and stay, more capacity might be worth it depending on what the cost is. Agree with another poster, unless you have dual AC, you can pretty much handle your needs with 30A as long as you manage your load in the kitchen and bathroom. Screw up and you unplug, reset the breaker, and remember what you did wrong. My only trips were when the toaster and the Microwave tangled or an electric space heater and a hairdryer were plugged into the same circuit. With only the wife and I, we have very few issues [with the power anyway].
