I've done this Ice Road a few times (not with TTI, just muckin around) and I've found it to be quite good. My advice is to make sure you have NO OTHER MAP MODS INSTALLED while running this map, as it screws around with the Economy file and we all know where that ends up...
Otherwise, it's a brilliant map mod that I hereby reccommend to anybody, especially those of you that are running the Ice Road this year (
, thats me!). Get ready to make the Dash for the Cash!
