HI, CAN ANY ONE EDUCATE ME ON THE BENEFIT OF A FIBERGLASS TUB OVER STEEL?

Hit your Caps lock key so your not yelling. But besides that the fiberglass tubs don't rust. Do some checking to make sure you get a good quality tub. Is this tub for a CJ5 or 7?
You can replace a 7 tub with a YJ tub they match up pretty well. I believe 1 set of out riggers needs moved. (Just from what I have read from other sites)

they don't rust but they can crack when damaged instead of just bending/denting. more difficult to ground items, but thats minimal. need special paints. mostly personal preference. i like working with metals so i'd lean that way. but fiberglass is easy to work with, with regards to adding small items like cb antenneas etc. where metal you have to deal with repainting (rustproofing) with every hole drilled. if buying fiberglass compare companies their are many differences in construction. some much better made for off road/hard use ve. show.
