Finally, I decided to not wait for the model 3 but go for a model X. I'm getting a blue 75D with white seats and EAP, no other options. The order is confirmed today and I cant wait for the delivery next month. Before the delivery, I have some questions for you model x experts: 1) How's the build quality of model x these days? I read it was pretty bad at the beginning with low yield rate and large gaps between panels 2) I plan to get a HEPA filter in the near future but I cant find the item link on the online store anymore. How do I get it? 3) Has anyone slept in the model x for camping? How much power does the AC cost in summer and winter if you run it the whole night? I want to use it to camp outside for astrophotography, but I probably need to be super cautious since my battery pack is the smallest one. Lol 4) I know range varies based on environments. How much range do you normally get? 5) Any tips on maintaining a healthy battery? Not to charge 100% at all?
