I own the same rig. You will see a post on here, search for Hazmat91180 posts and you will see my setup.
I really like the unit. I would go 50AMP and Two ACs if you are going to be camping where it is very warm. I am northern midwest so I am ok with one ac.
The diamond package I could not get them down in price and I liked the option of white versus the brown being in the sun (we do a lot of non shaded spots). Not sure if it makes a difference.
I HATE the couch in the living room to be honest with you. perhaps I would like a non-leather option, but I seem just to slide right out of it.
I'd ask the brand of TVs they put in them. It seems I lucked out with LG but sometimes they stock them with different ones.
See if they'll upgrade the thermostat for you in the deal. get a digital and just knock out that upgrade now. The manual just cycles and cycles and it gets annoying fast.
One thing I will tell you, this rig IS HEAVY. my tongue weight is over 1000, I would stray away from the Equalizer 4 10K, go right to 12 or even 14K. I tow with a 2015 F150, and I am barely under weight. Not enough for my liking and will be trading the truck in when the lease expires. I tired to have a daily driver and truck and I guess I'll go back to two vehicles (very tight parking garage)
