I am happy with the Mag Hytec. I have used one for several year and have put them on others' Rams and everyone has been satisfied. Being cautious and unlucky, I put silicone RTV on the cover in addition to the o-ring. Roy shook his head when I told him that, but I have not had any leaks. Last time I took it off, I left the o ring off and just used RTV. I like the 1/2" thick cover for strength too, and wonder what would happen if I backed into a rock while 4 wheeling and hit a cover with a sight glass on the glass part. I have not seen the Magview close up so can't comment on it directly.
Joe, if you backed into a rock, the stock steel cover would dent, the Magview and Mag Hytec would probably crack just like a trans case or tailstock.
Biggest advantage is added oil capacity.
But I haven't had a lick of problems with the stock setup. Maybe I'm just lucky but I can think of many things to spend 200 on other than a fancy cover for the differential.
