<h3>Suburban Mfg: Trusted RV Appliances Since 1947</h3><p>Few names carry as much weight in the recreational vehicle industry as <strong>Suburban Mfg</strong>.

There.was a bit of miscommunication between sales and shipping departments, but my order was filled and shipped as stated. Very low price, in fact the lowest on the net, and I did alot of research.
