Look people, any -other- relay that costs $6.99 is good for 30-40 amps in the NO contacts. There would be nothing wrong with this relay at 50-60 amps load. Your tires are good for "X" MPH. Do you -ever- run them at anywhere near that? This is a great relay for the price. Legitimate charge splitters battery combiners smart solenoids are the only way to go for dividing battery banks. They use a forty dollar (retail price) tower solenoid like an Essex. 8:20 this morning, I used my MOSFET relay to start a Ford Ranger pickup. Eight 172 ampere (hypothetical rating)MOSFETS with short legs connected to 1/2" square copper bussbars. Solid state is the way to go to stop arcing. Box is a deep quad receptacle. No moving contacts to ever deteriorate.
Tower-type power relays are great until affordable extreme amperage solid state relays come along.
BTW out here on the peninsula a second Kountry Koach has joined the 1st on the beach I see, worth 5-7 hundred thousand dollars. Three axle diesel pushers. They look like customs builds.
Having a head-on in the USA with a Peterbilt is a hell of a lot more likely than running into a barricade of mounted banditos adorned with bandoliers, rocket launchers, gold teeth, and silver horseshoes on their mounts.
90% of highway problems occur between dusk and dawn, but know-it-alls ignore common sense pay a heay toll then run home screaming they were "ultra'careful".
