Looking to buy new 3124KB

[earlfo]

Any and all help with the following would be greatly appreciated.

Best time of year to negotiate a purchase?

Any help with dealers that are good to work with for both service and pricing?

Any thoughts on negotiating the price?

So these are the optional items:

I'm trying to determine which one's to get in the new TM and which I would be better getting aftermarket:

Low profile roof air conditioner
- I will be working sometimes in the trailer so a rather quiet AC would be preferable for when I need to have a conference call.

Awning
- I assume this would be a TM item

Electric tongue jack
- any thoughts?

Hanging kitchen cabinets
- I assume this would be a TM item

Plumb w/quick connect for outside grill
- I assume this would be a TM item

Rear bike receiver
- I assume this would be a TM item

AM/FM Bluetooth Stereo
- any thoughts?

100 watt solar panel w/digital control
- any thoughts? Quality of products included from TM?
- has anyone upgraded beyond this to higher wattage?
- External vs roof mounted?

Hanging LCD TV mount
- any thoughts?

Front window w/curtains & stone guard
- I assume this would be a TM item

Digital HD TV antenna with booster
- I assume this would be a TM item

Cassette toilet in place of regular flush toilet
- I plan on sticking with the toilet it comes with
