As has been explained, it would be pointless to pay for a 50 amp site - you cannot pull more than 30A. Now if you opt for a 50A site you will probably pay more if those sites are limited. Many parks only have a certain number of 50A sites and those are more regardless of what you plug into them, some have 15, 30 and 50A in all pads and some have no 50A at all. Just go with the 30A and use what you can depending on the site's ability to deliver power.....make sure you have an EMS/surge protector.
