What Size Wire 30amp
I would like to put a 30 amp RV plug on my garage. The service pole is about 80 feet from the garage. I was wondering was size wire I will need to support 30 amp service.

It's not really a few dollars more, it's a few dollars more per foot. So about $200 extra. I know I'll never have an RV big enough to need 50A service so for me it would be $200 wasted. Plus 4/0-4/0-4/0-2/0 outdoor cable is an absolute PITA to deal with so the install will be much more difficult than a simple 8/2 pull. The weight difference is also significant, 0.2 lb/ft vs 1.0 lb/ft.
