The level up 6 point leveling system is "just shy of $4000 (according to posts of people who have had it installed)
If you're going to be doing any hot weather camping, the extra roll out awning is always a nice addition, a "built in" air compressor will definitely save having to pack one that is always in the way, welded D-ring tie downs would beat the "screwed to the frame" type in almost every situation, add a dedicated outside TV and electric heat pads on holding tanks and it seems like a "thrifty package" even at $3000. But the website and the brochure indicate it's a "free package" (at least according to the sales hype)
It appears to be a "special offering" for a limited time with no additional price. There is an optional Ramp Door Patio Package for $3375. Could that be the added cost you found?
As for the "free Monster Package" I'm sure somebody is paying for it, <G> but most of the add-ons seem to be things that would make camping more convenient and add to the cold weather function. I'd say it sounds like a nice addition if it's really free
I can't say the same about the dual A/C with heat strips option though. A 15K BTU A/C is about $700 and heat strips are about 100 each, so the price of $1100 seems a bit high for that part of the optional package. Of course, if it also includes the ducting to tie both A/C's together in the roof air delivery system, then it may be worthwhile to have the option of using the A/C in the unused part of the RV to cut down on noise while in the other part of the RV and vice-versa. But if the second A/C is just a ceiling mount without ducting throughout the RV, it's probably cheaper to add it separately.
