12' Ttt Named "Freedom" Help Wanted

[Sporty Modder]

I am in the planing stages of building a Ttt, i have some sketches for layout and dimensions, and I have an idea on construction methods. Only things I am having trouble sourcing is grey water/fresh water and sewage tanks and the sizes needed. I have a history in termite repair so wood working is not a problem, my father inlaw welds, so that won't be a problem. I am thinking about using 1\8" plywood on the inside framed with 2x2's 24" on center with 1 1\2" foam board as insulation covered with fabric and titebond 2. I want to keep it about 2000lbs loaded. Oh we plan to live in it. So maximize space and storage while keeping it fairly roomy.

Going for a modified weekender style with some aero treatment on the aft 4ft and front 2ft. Overall inside height @6'1" and 96" overall height, floor is 18" on the utility trailer i am using, and 96" wide fender to fender. 12' long not including the tongue. My wife wants a toilet and a sink in it, not to worried about a shower, a removable stove so we can cook outside when we want, and a refrigerator/freezer, and fold up queen mattress over a table /bench's.

I used the Valterra ABS tanks purchased through Amazon. They are available in a range of sizes in a fairly flat configuration. These are actually fresh waster tanks with the standard three 1/2" threaded fittings but can be easily adapted with the larger ABS fittings. For black water just be aware those longer than 30" have an internal baffle than can be cut back when you add the 3" inlet and drain fitting.

There are also a number of suppliers of ready made tanks on Amazon and e-bay so you might be able to find one that meets your requirements on the shelf.

You might also want to look at the combination toilet and shower pans. They are made with an elevated side for the toilet and a matching black water tank attaches directly below. These would mount at floor level so if you need additional black water capacity you could add another tank below the floor. You could drain the shower and sink(s) into the separate below floor tank using waterless traps.

Not mine but here is an example of the combo pan:

Thank you for the reply. I will be looking those up.
I will be posting pics of my utility trailer and tow rig here soon.

Here is the truck and trailer. Truck is a 96 4x4 B4000, with a 5spd mt. Trailer is 8' outside fenders and 10 ' inside the box.

I am assuming that you are using the utility trailer for your build, Are you going to work around the top rail? Or take them off?

Yes that is the plan. The rail will be coming off, as will the tailgate. My budget is really tight right now, cannot even afford a pack of cutoff wheels for my grinder, lol.
