I just went through this painful process of getting a tub. The best one out there in my opinion is from CCOT. But it will cost you $10k. I did not have that budget. I then looked at Vintage and Land Cruiser Heaven. Both get tubs out of Columbia I believe. Covid had slowed them down a lot back in April. I also had communication issues with both companies. My gut told me not to buy from them. Since I’m not doing a trailer queen restoration, I went with an aluminum tub from Aqualu. Tub arrived in 2 weeks. Crate it came in was beat to all heck, but the tub had only minor scratches. Mounting holes lined up nearly perfect. It’s very well made and I had my original trans cover modified to fit the tub instead of using the cover that comes with it. Hope this helps.
