Given a single rear wheel, there is essentially no roll stability at the rear. Since it isn't a 'tilter', the front axle (w/two wheels) provides the only roll stability for the entire vehicle. Also, the 3-wheeled configuration gets complex when suspension is involved because the suspended front axle will allow a given amount of roll, exacerbating the tendency to lean in corners. Just a suggestion, but I would strongly encourage a minimum weight distribution of 65% front/35% rear, and a stiff anti-sway bar on the front. Yes, agreed, keep the mass as low as possible... especially on the rear half of the chassis.
At 500 lbs total, you can probably get away with using bathroom scales under each wheel. This will easily ballpark your weight distribution (given approx. 33% under each wheel). If only one scale is available, just make sure the vehicle is level by using blocks or spacers under the other two wheels when weighing.
