Cyanlabs has a tool that upgrade from 3.0 to 3.4 go to their website and download the application on your PC and then go through the information on your Sycn 3 system and it will create the package for a USB. You will need I think 16 GB at least.
Initially the bed looked like it could be as long as 6-foot similar to my 2nd generation Ranger, but scaling off the rollback tow truck, it may be as short as 5 feet, maybe a little longer. Overall truck length appears a little shorter, though wheelbase roughly in same range at +/- 9 feet. The rear overhang looks shorter to me, likely accounting for most of the difference in vehicle length compared to my Ranger; granted only rough estimate based on scaling off picture taken at an angle.
A video mentioned more information will be disclosed by manufacturer on April 23 if I recall correctly, which hopefully will include some specs like battery capacity, targeted range, dimensions, etc.
