Why 2 or 3 motors and what motors?

Towing power for what? You move houses for a living where you need three motors?
What are you towing (incl weight)?

Tesla is a bunch of car guys who have no clue of what a truck is. They cite 0-60 times on the Semi...like a trucker GAF.
In my experience, towing more than 2x or 3x the truck weight is asking for trouble. I doubt your little sawed off Jeep was ever rated to tow more than 7000lb. As soon as you hit 2x, things can get squirelly pretty fast in curves going down steep grades with trailer push.
You clearly havent done the math on your solar powered camper. A set of foldout panels means next to no battery at all. LED lighting means you use maybe 40W of light for 8 hours...that's 0.33kWhr of battery...one Tesla module has you in lighting for 17 days...55lb. That's with zero solar. A PTC would nominally run 2kW for 12 hrs at night. That's 300lb of battery
Get the tow weight goal to a max of 4,000lb and target 3,000lb. Being sloppy with mass has no place if there's an EV in the equation.
Two motors if you need AWD, one is fine for highway work, gear it to top out at 80 is good.
Your problem will be cooling, not so much the battery...if you're not sloppy with the camper build.

It's all on here - several people have tried to organize "instructions", but everybody's requirements, vehicle, budget, resources, skills, tools, and regulations are so different it becomes more of a reference than a recipe.
Best thing is to dive through entire build threads to see what people did and try to understand why. Doesn't have to be the same vehicle, though it helps to look at Jeeps vs the Lambo conversion, for example.

...and brakes, and frame reinforcement, and cooling and ballast.
There's a reason a Ford F-450 weighs over 8000 lb. Empty.

You may need a multispeed to crawl up/down a steep (6%) grade with a heavy trailer.
FWIW, my F350 Ford smoked the clutch (to where I was forced to clutchless shift in Illinois to keep what little clutch was left for launch) going up Vale Pass on I-70 in Colorado while pulling a heavy trailer. 6 speed manual. The problem? Not dropping a gear or two vs going 55-65mph up the hill and having a torquey drive element (diesel). Makin' time, baby! 😂
