William - Frankly, I think it's more important to get the correct size inverter for your needs, be that a 1500w, 2000w, 2500w, or 3000w. Obviously, it should produce a Pure Sine Wave (PSW) current for many of today's fussy electronic devices and it needs to be "balanced" with the size of your coach's house battery bank. Whether it's a Magnum or Xantrex or Victron manufactured inverter is about as important as drinking Coors or Bud, IMO. I got a Xantrex because that's what my installer recommended.
