No release date yet, it takes some time and I am now throwing a full time job into the mix. You'll know when it comes out, just enjoy the current skins for now.
Actually, this does do with this thread. There is a Bounty Hunter Trophy Truck in this pack @Crashmaker although it currently isn't downloadable. Pack updates are delayed further due to a loooong work schedule.
Not a whole lot atm, but the band themed skins and @Nathan Hils Monster Energy are uploaded! I've been helping others pack some new skins (thus delaying Bev/HGTS Crew), so be on the lookout for those!
