I have a 3 gal and a 6 gal Atwood tank in the new style. Yes, they certainly do bulge, especially in the summer sun, but it's never been a problem. Atwood recommends using a "thread sealant" but I don't know for sure what that is --- teflon tape? liquid sealant? I don't remember what I used, but they don't leak fuel, even under pressure. Fifty bucks sounds like a good deal. Most places sell them for a lot more.
