Usually by the time you get to the point of asking this question, your Jeep is too far gone to be a vintage, classic vehicle. And glass is great for builder Jeeps.

I have a 1980 CJ7 with a fiberglass tub. I was planning on building it up.

I also have a 1960 CJ5 that's 100% stock. It would be a shame to make that one fiberglass.

There are pro's and con's to both. Steel, Aluminum and Fiberglass tubs vary in price due to quality and fitment. Obvious with a fiberglass tub you never have to worry about rust again. I have heard that they may be a pain to install over a metal tub due to fitment issues but again that is probably one of those things that you get what you pay for. New tubs vary in price from $1500 to $3k+.

Another popular option if you own a cj7 would be a YJ tub swap from a 87-95. They are almost a direct fit and cost much less than a new tub. Lastly would be to buy replacement panels but depends on your level of rust and amount of work you want to put into the Jeep.

Remember that fiberglass doesn't conduct electricity, so u have to run a ground wire to the chassis for all ur electrical components.
Aluminum tubs are nice, light weight, and also don't rust. However, they are pricey. And unless ur good at tig welding aluminum, everything u add to ur tub will have to be bolted or riveted. I have never seen an aluminum tub in person, but I would question the manufacturer about how they fasten threaded inserts (like where u bolt the fenders, dash, and seats) to the tub. I'd prefer slugs welded into place with steel timecerts (? Much stronger and more permanent than helicoil) installed as opposed to a steel nut caged in place. Those will drive u nuts (no pun intended) if they ever break loose.
I'm sure u know all there is to know about steel tubs, not much to explain there.
Good luck with ur purchase, keep us posted on what u decide on.

I like the metal body, as you can anchor things to it at just about any location. In some clubs I have been a member of no fiber glass tubs were allowed for safety reasons on the trail, as they felt things like mounting brackets, even those reinforced, could still pull out of the tub.
