The US laws on bumpers has been refined in blood over the years. At least 20% of the people I know in my area have damaged their car by hitting a deer.
How will this truck fare if hitting a 90 kg deer? It's different enough that it might be substantially different (better or worse) than a more conventional truck.
I'm also reminded of a famous car made of paneled stainless steel. It was a terrible car and ruined the company that made it. It's only remembered fondly because of a popular movie series.
