Seasick’s numbers are pretty good, except the dry weight of the 208 is 2650 lbs for your vintage hull, not 2000. Here’s what I always figure for heaviest case:
Trailer 1100 lbs (I have a Pacific galvanized trailer)
Hull 2650 lbs
Motor 420 lbs
Full fuel tank 500 lbs
Full fresh water tank 80 lbs
Misc other gear 300 lbs (batteries, oil, anchors, and other junk)
That puts the rig at right around or a little above 5000 lbs. I tow with a 2012 Ford F150 Supercrew with a 3.7 V6 rated to tow 6000 lbs and can hardly tell the boat is behind me. The long wheelbase helps quite a bit. I’m sure you’ll be fine with your 4Runner if you take it slow and give yourself plenty of braking distance. But you are going to be up against the tow limit. Obviously you can shed a few hundred lbs if you wait to fill up the fuel tank close to the ramp and keep the water tank empty, if you’ve got a fresh water shower. But, also pay attention to the GCVW for your vehicle because even if you’re just under 5000 lbs on the trailer, your combined weight of the vehicle and trailer might be over.
