I had a customer ask a similar question, if it was possible to do a particular job, my answer startled him, I said anything is possible, all it takes is time and money, how much time and money do you have. Surprisingly, I never got the job.

Sorry, I can't help you on the trailer question, not enough information (at least for me)

I would imagine the trailer alone would be a load for a tundra.

You don't need to do a thing to the rear axle other than remove the driveshaft. It has oil, it was designed to go down the road......

If your worried about parasitic loss then chop the axles off and bolt the flanges back on.

The biggest issue I see with all of it is how the hell are you going to STOP? The neighbors trailer is mostly used behind 7 ton farm tractors, generally plenty of braking there.

The best setup would be an electric over hydraulic rig, which at the last time I priced a unit was about $750.

As to pricing a custom unit, unless you have built two or three you have no idea how long or what materials will be needed. Your fab guy prolly trying to cover his arse just a bit.

If you were pulling it with a tractor yes it is possible to build it into a dump trailer, but pulling it with your Toyota would not be wise. As mentioned before in this thread the axles would have to be moved to make it more stable, if you were going to do that it would be wise to swap out those axles for regular trailer axles with electric or hydraulic brakes.
Once you were done modifying the frame, axles, hydraulics and getting all the inspections done you would be looking at more than the price of a manufactured dump trailer.
Parts and materials will run into a couple thousand + labor to do the work.

I agree with Dan. Not wise. A few years ago, I ran into a deal on a 10k equipment trailer, so I got it. I pulled it with my 1/2 ton Chevy. That lasted a very short time. Behind the Chevy it somewhat had a mind of it's own. The good part was I had put 2 brake axles under it instead of the singe brake and single idler that it had. Then I ran into my x cab 3/4 ton diesel Chevy. What a difference. I would drag that thing anywhere. Still would be better with a dually. Personally I would pass on the dump trailer. I would first look at fixing what you have. If that won't do, look at swapping to another cab and chassis. then third look at a used dump trailer.

No way I'd pull a beast like that with a Tundra.

Your fabricator has questionable judgement if he's trying to sell you on that being at all practical. I'd walk away and not revisit the subject with him. You were wise to ask here!

A trailer is an answer to the question "what do you need to haul?".

An experienced person could put that dump box on an appropriate gooseneck trailer chassis, but there's no reason to pay someone to do that since it would destroy any potential savings and it's still too large for a Tundra.

That shouldn't be hard to sell if the rest of it is in good shape. You could check out used truck dealers, for example. A dump is worth more than a flatbed.
