[VAC] Air Conditioner Question

[Marvin Murray <mwm@xxxxxxxxxxxxx>]

Hi-

I've just about completed restoration of my 76 Tradewind 25' and have 
encountered an air conditioning problem. It still has the original 
Armstrong unit which seems to work fine, except: after running for an 
hour or so, it trips the circuit breaker on the panel in the rear 
bathroom closet. If I reset the breaker, it runs fine again. Any ideas? 
If  I have to replace the unit, what brand/model would you recommend? 
Any help would be greatly appreciated as its 100+ degrees here in Las 
Vegas:)
