Hello all,\nI've put a trailer hitch on my 2004 WRX wagon, though I know that the\ndealership does not recommend it. I've heard this is due to the turbo,\nbut I am unsure why this is the case. If I haul a boat (not a huge\none-\-outboard motor on an aluminum boat, not sure the weight) twice a\nyear for 3 hours, is this potentially damaging to the motor? I've\nheard if I do drive, I should drive at high rpms to reduce strain on\nthe engine. Does anyone have suggestions, thoughts?
