electric PU that can tow 11,000lbs

I would be shocked if it got 60 mile range pulling a 11k travel trailer (as opposed to a low flatbed type trailer). Then again 400 mile range is only a prediction not a tested fact. I can announce I am developing a truck with a 2000 mile range...until I actually put it out, it's just talk.

Plus with a 1760lb payload....an 11k trailer will have around a 1500lb tongue weight...leaving 260lb for passengers and other cargo. At least the current 1/2 ton trucks can be configured to get north of 2000lb payload, so you can legitimately tow 10-11k trailers.
