I have recently acquired a 1972 Hunter Compact 2 and may I add it needs a lot of work. I have put in new floor (wood floor rotted out) and am in the process of finding a new door for it. The crank up top has been removed and someone enclosed it as permanent pop up but that's ok, my main concern is that it is wired for 12 volt, it has a breaker box under the kitchen sink but nothing to convert it to 110 volt. Any cheap or ingenius ideas as to how I can convert it to 110 without spending a lot of money on the original converter which, by the way, from a local camper sales and service place they tell me it is around $275 IF they can even find one for that old of unit. Any ideas??
