Time to replace furnace in 1969 21’ Globe Trotter and have narrowed choice (I think) to Suburban NT series and Atwood Everest series. Both are direct discharge with electronic ignition and come in 12,000, 16,000 and 18 or 19,000 BTU ratings. Suburban claims to draw 2.8 amps, Atwood 1.8. Is this a significant difference or are both acceptable/unacceptable?
Interested in any feedback on one or both units - any plusses or minuses? Also, which BTU rating would be preferred?
