55 inches is long enough to haul a pallet of material, but I also like to use my truck to pick up a yard of gravel, mulch or other materials. I'm concerned that bulk suppliers are going to balk at loading a 55 inch truck bed with a standard 72" wide skid steer scoop. As someone who plans to do real work with my R1T, I'd happily trade a shorter frunk for an additional 17 inches of bed length. A six foot bed is what I've had on my trucks in the past and always found adequate.

Fifty five inches is also shorter than the average length of an adult bike: 65 to 71 inches, though with the front wheel turned sideways, I'm guessing I could still throw my bike in the back bed of the R1T when I'm in a hurry and too lazy to mount the bike on a rack.

A Ford Lightning sounds like a better choice for you. I don't believe that Rivian has the resources and money to make a longer bed version. The R2 and R3 hold way more profit potential for Rivian.
