Hey guys. I'm new to the forum. Thinking about buying an '06 quad cab trx4 off road w/ the 4.7L engine. My brother mentioned the 4.7 could be hit or miss. Says he heard of a few people having trouble w/ them. I could use some input/advice. Also, I know a lot of them rot above the rear wheel wells. It has a little bit which I plan on getting repaired, any where else that is a common place to find a lot of rust to look out for?
