My "been there, done that" comment was directed towards the effort of looking for a Toyota to use as a toad. We pulled our 86 Toyota PU for a couple of years (4WD with man transfer case), and even pulled my Tundra one year by disconnecting the driveshaft at the rear end. We contemplated putting our Avalon on a dolly, but decided against it.
No disrespect to Remco, but I would never make a decision based upon the word of a salesman or person from the company. You need real world experienced people to guide you.
Good luck
