I have the halogen headlights and I agree they are pretty pitiful (although I think they look nice). Full suite of cameras is worth the money. Blind-spot monitor indicator is hard to see. Lane departure warning feels cheap to me (and picks up alternate "lines") so I turned it off. Factory spray-in liner is nice (and relatively light) but adds to the build time (offsite vendor). Definitely get the 5600# or higher front axle if you're getting a CCSB diesel to tow a fifth-wheel (you can always swap down to 5200# springs). The 5200# axle isn't an issue for travel-trailers as you can "reload" the front axle via the equalizers to taste. Frame-mounted fuel filter change is really easy... just need to drain it first as per the instructions (I've changed mine without issue).
