Personally I don't know TG's support and tech for their product line, but they have really cool tent's. Marlin's tech support is unrivalled for 2 reasons, Marlin's staff knows what they sell and this board. This board is support for anything MarlinCrawler sells, most members here either have done or helped someone install the products sold here. You can't beat that type of support, real life install tech. If you ask here you could find out the issues that will arise before you even make the first twist of a nut. I think (don't know for sure) that TG can only hope to build such a large free tech support that MC has.
