It wouldnt be difficult to enclose the back of that trail boss EV avalanche truck they have. It’s horrible on anything past a fire road. The truck is 100k I’m sure the burb would cost more..Looks like GM is bringing an EV suburban to the US market in 2028.
The only specs that I can find are the battery type and a blurb it will be a longer wheelbase. No pricing as of yet.
