Cool fiberglass tub or steel tub

My first car I bought myself was a 84 CJ7. Jobs, marriage, kids etc made me have to sell it. Well 30 years later, job still good, divorced and kids grown, I'm ready for another 84 CJ7. I have noticed on a lot of restores some have used a fiberglass tub and some steel. Can I get opinions on pros and cons of both. I have a buddy who has a 84 that he started on but now needs to sell, and it needs a tub. I thought the price was right $2500 (going to see if he would come down to 1800) and I would have to get a tub for it. Your thoughts?

I will never feel comfortable in a fiberglass vehicle. If I ever got in an accident, besides the fact that the Jeep isn't up to current safety standards I can just see the fiberglass breaking into a million pieces. Nothing compares to having that strong american steel keeping you safe, especially when you roll. If you think about rolling with a hardtop the first thing that breaks is the hardtop. Now I am sure the fiberglass tub is made a bit differently but I just still don't feel safe at all without the steel tub and front. Also I love my tailgate.

Thank you, you gave me another perspective on it. Never thought of the safety aspect of it. I think you just answered my question. Steel all the way. Take care.

the safety factor does not bother me much.I had several corvettes over the years.No tail gate on a jeep? No,I don't think I would like that and I know my Lab wouldn't

I have a 1977 cj 7 and replaced it with a fiberglass tub. I take it out on the trails very hard and have never had a problem. I had my roll bar welded to the frame, so safety was there. It is not my daily driver. One great think about my fiberglass tub will never rust. I live in IL and there is a lot of snow and ice.
I think it's a great investment, depending how you will use it.

When I bought my 77 Cj7 the PO had a fiberglass tub on it, and I didn't think it would be that big of a deal, until i had to work on it, where the clutch goes through the firewall it must've flexed wrong or something and pulled it out so i had to grind the body back and install a steel mounting plate to keep the clutch pedal in place, in the winter months i put the hardtop on but it doesn't sit quite right like it should, one side is up higher than the other. where the soft top rails mount to the body most of the mounting holes have the hardware in them missing or stripped out. NOW I'm not saying don't buy one, i know i wouldn't... but i don't know the brand, how old it is, or anything like that. but from going though the rest of my Jeep I figured out the PO had absolutely no idea what he was doing...

I wouldn't be at all adverse to a glass tub. Yes, there are certain things that need addressed. A frame mouted roll bar or cage, you don't want to hang the spare off it, and you need to run ground wires to everything.

I put a glass tub on my 3B back in 1974-1975 and it's still fine. The fenders tend to get a lot of star cracks in the paint but I suspect if one used some quality bed liner on the bottoms that wouldn't be a problem and I run ground wires to everything these days anyway. I did build a 1.5" square tube steel frame under the cockpit area that mounts the seats and harness, along with the sill sliders and exhaust skids and my spare carrier is supported off the frame and roll bar.

It doesn't have a tailgate but I have not found that to be problem for me or the dogs.
