did you accidentaly start a new thread because
several of us chimed in already on a thread you started earlier http://www.naxja.org/forum/showthread.php?s=&threadid=6063
and based on that thread I would say they have different pro's and con's
Durango - owners complain of bumper flex with swingout
- really good corner protection w/1997+ style corners
- heavy expensive bumper
Bulletproof - solid mounting, rattle free swingout, no flex complaint
- much less corner protection
- heavy expensive bumper, though slightly less so
Any modification is a personal choice. pick your own poison.
