Our 2013 Newmar was offered as all electric only when we ordered and bought it new in 2013. I was concerend about not having propane after having Class A's for 20 years prior and having propane refer/furnace/bbq grill/griddle,etc.
Now, 10 years later, I have no concerns. Everything has worked OK, I did have to buy an electric grill, and now I have and electric griddle, air fryer, slow cooker and other odds and ends. Refer is huge and works great. Now, we pretty much always are at a FHU site in out travels, which are typically 8-9 months a year.
