I'm raising tilapia also. I got mine from a place out in Kansas I believe. I can look that up if you need me to. Not sure how the border crossing would be though? My door is also 32" so you will have similar issues that I did. The IBC is easy because once the top is cut off you can fold it over some for extra clearance. What is the issue is the cage. I cut my cage just above the first cross bar and just nearly got it in and down. Mine was a 275 gal. model, the 375 will be even taller. I could hold about 225 gallons in the tank but would need a top to prevent jumping. I keep about 150 gal. now and have a 75 gal. breeding/nursery tank also. Good luck. I'll be watching your progress.
