So random somewhat technical question... is the 12v power lead on the trailer 7 pin connector switched or always on? If it stays always on, it could be a convenient way to keep a travel trailer powered during dry/boondock camping for extended trips. If we could arrive at the site with the MX even moderately charged, car would power the trailer for weeks with typical loads. My previous camper had 200 watts of solar with dual group 27 batteries, but obviously this can't compete with a 100kwh battery feeding the step down D.C.-D.C. Converter. Second question, if it is switched power, does it come from the accessory rail with the 150watt limit or does it have a separate relay? Kind of random, just trying to figure some things out prior to taking delivery in July.
