You should be fine. Most any 2wd standard can be towed by putting it in neutral, turning the key on if the steering wheel locks and you may have to pull a fuse or disconnect the battery so the dash lights and stuff don't drain it. I did take a look at Remco's site and it does say "towable as is". So you will need a baseplate, tow bar and wire up lights. For lights there are some options. Diodes to connect the existing bulbs, install secondary sockets to add bulbs or magnetic lights come to mind.
Check the tow capacity of your MH to make sure the 4Runner isn't too heavy before getting started.
