I don't know, but when I see reflective tint - first thing that comes to mind is 'gangsta'..... if you are going to tint your windows - tint em with the normal window tint as curtains and hooks just sounds like too much work / high maintance.
I believe every window is legal to tint except the windshield, drivers and passenger windows in all 50 states but I could be wrong on that.
You mentioned that you have a dog - that's your burglar alarm.
Don't do anything that will make the inside of your jeep turn into an oven.
Truth be told - I still do not know what's worse - having tinted windows or not having tinted windows - as my 90 Jeep has 'em, and it gets stupid hot in there.
Does your dog like to travel ??
Mine gets scared and really just likes to stay at home or just go on local trips where she sits up front in the passenger seat.
Make sure you have a good amount of room for your dog so your dog will be comfortable if you'll be taking long trips.
That being said - I'm in favor of minimal seats.
Does your seat truly fold down - like those old school station wagons - where you then have this huge flat surface you could put a fulton mattress on it or does it kind of just fold up forwards - like the CJ Jeeps ??
If the seat only folds forwards and not flat, I'd personally get rid of it - unless you plan on traveling with others....
Also - keeping gear on the roof - keep in mind it's then exposed to the weather, and keeping gear on the roof also attracts attention depending on where you are parking for the night.
If you are going to keep gear on the roof, try to get some real good dry bags from a rafting or canoeing company, they will be expensive - but well worth it, plus they will look good tied down on your rack - as opposed to a bunch of bags etc...
Also there are some very good cable lock systems out there that work like a lasso that you can secure your gear with as well if you choose to go the dry bag route.
Good luck with that jeep - she's beautiful - and very practical.
