I currently have the Suburban P-30 furnace for my motorhome and want to upgrade. Which is better the P-40 or the 2456A Suburban Furnance? Last Updated: 11/07/2014
The P-40 and 2456A are actually the same part. There is no difference between them. P-40 is the model number and 2456A is the manufacturer part number for this Suburban Park Model Ducted Furnace.
