Here is a running list of stuff I bought + an estimate price.

I didn't have the best experience with Amazon when I had to return items, so if you can buy direct from the company that makes the product (example buy from Renogy directly on their site for the solar panel). I think that's better. Amazon is solid for customer reviews and ease of finding it. Not always the company I buy from in the end.

Honda Factory Roof rack (mine used from ebay) Link: = $140

Maxxair Delux Fan = $300

Cargo Carrier (used from craigslist, similar to packasport ) but here's a good option = $275

KeyLine Battery isolator : = $200

Tri-fold 4 inch mattress = $80

Solar Panel : Link (renogy) = $200

Aeiusny Generator Battery : = $280

100 amp hour battery (renogy) == $215

Wood for bed and shelves (Melamine from Home Depot) = $200

Dometic drawer fridge : https://www.westmarine.com/buy/dometic--cd-030dc-drawer-refrigerator--10855823?recordNum=19 = $700
