Had numerous Subies and never a single problem, from Forester, to Legacy, Wrx Sti, and now 3.6L tribeca. I also own a chevy pickup that tows my 23' boat and 27' TT. Never had issues with berings, head gaskets etc. All, and i mean all smoked little blue at startup for around 15-20 seconds - boxers are common for that. All my subies got to 200k without doing anything. No timing belts etc. There is a reason why subies are popular in snow infested areas. They're the best at that. As for towing with one, i would never tow with a Awd vehicle. Too much wear on awd power train, not efficient.
As for the post about transmission not having a gauge, i call it BS. Every subaru has red AT Temp light on dash, turn your keys to light up dash lights and you will see.
Also, if towing a small utility trailer, or going on long trips with your Subie, you can pull AWD labeled fuse, that will disable awd, and make your Subie FWD only
