Ok, so starting to get excited now, as my new Puma arrived at the dealer this week! Had to go check it out and take some measurements!! LOL
Anyways, I ended up answering my own question about the tv size restrictions and thought I would post them here in case anyone was wondering.
On the 2019 Puma 32bhdb model, the living room entertainment center tv opening dimensions are 39.5"W x 32"T x 8"Deep. So, long story short, most new 40" flat screen tv's will fit, but barely. Personally I don't like the "look" of a 40" tv in there as it's a tight fit width wise and I will opt for a 32" instead, as it looks cleaner.
Now, in the bunkroom, the tv area measures 37.5"W x 25"T x 12"Deep. Again a 40" flat screen will fit, but it completely fills the opening. Again I'll opt for a 32" for a cleaner look and not too gawdy, lol.
Can't wait for camping season to get here in Indiana!!
