We have a 30,000 BTU Suburban Furnace which is still under 2 year warranty. The problem is that our little 20 ft 1972 Shasta can't handle this furnace. It is a very nice furnace... we have all receipts and warranty information, it works great and has tons of great reviews online. I've seen the same unit posted for sale 600-900$ else where. We are asking $350--OBO. In person transaction--CASH offers only please. Many blessings,Nick and Candice
