Umbilical and 7 Pin adaptor issues

The flat is 20A rated, where the round is 30A, sometimes 35A rated. That's a 33% increase in amperage.
For those the have 12V fridges and electric/hydraulic brakes, the 7-pin round is a must have.
It is still a good idea to carry an adapter from 7-pin flat to 7-pin round, in case someone with a standard connector ( which sadly is a 7-pin flat) needs to rescue you.

Uwe & Andy -- I'm so glad I read your posts about the round pin connectors, because when I went to a trailer supply place today to buy a truck-side connector to go with the round pin connector on the Caravel, the guy spent 5 minutes trying to convince me that I did NOT want a round pin: they were far inferior to the blades, corrode way too easily, you have to saw them off after they corrode, I definitely need to switch to the blade type, blah blah blah. I just smiled, thanked him for his time, bought a round pin connector, and left.

Keep in mind that these two very useful fluids perform different tasks well. "WD" stands for Water Displacing, and leaves a protective residue. Good for protecting tools and rustable metal, but the residue is only a lubricant until it dries. Then it's gummy until it's sprayed again. LPS is great for improving electrical conductivity, as in contact points, and connectors. Compounds like spray silicone improve sliding coefficients, and are properly used to coat table saw decks, or jig saws. That's why it takes a large cabinet to store all the "spray-ons." There is no single product that does more than one, maybe two, tasks well. jsutro
