This needs about 4 ROTV and a few SOTM/BFTU for extra grass/water/rock/sand, although an extra ROTV or two would cut down on those requirements. The VW part is optional, but if you do include it you only need one. The tundra is 1 TT plus many double hex snow tiles from figure packs. Besides all that, you need 2 RTFF and 3 FOTA also.
