Would have to look at one in detail again, but making it 6 inches shorter is not not helpful at all.
With payload now reduced to being essentially the same as my Lightning, and eventually when Fords can fast-charge at Tesla stations, there is not going to be much reason for me to want the Tesla. Even the short 240 mile range of my "SR" Lightning is not a big deal since 99.9% of my driving is within 20 miles of my house.
Next new truck for me will likely be when somebody starts selling 3/4 ton class electric work trucks with higher payloads and longer beds..
