13k xp to go for the Tiger II. Getting there. I can see the light at the end of the tunnel! Been working on my 3001P too. Its not a horrible tank with the last engine and 10.5cm gun. Only a near terrible tank. LOL Unfortunately the engines do not carry over to any other tank. Best to go with the 3001H where engine upgrades count towards future tanks. Still need about 37k xp for the DB.
