Jack, one of the things you will notice with the Voyager vs a true trike is the fact that with the center wheel being the drive wheel, and no differential, it requires more force to get one of the rear tires to slow down while the other one speeds up, the good old law of inertia! You will also discover you need a lot bigger turning radius. Keep the rear tire out of ruts too!!
The Voyager is a lot cheaper than a conversion though!!
