This trailer saves 7000l of diesel per year. Assuming 40l/100km, with this trailer you can go ~17.000 km more, which is 11-17% more, for the same fuel cost. Or ~12-15k EUR in fuel savings per year (assuming 1.8EUR/l).

With 13+ years ROI (electricity is not free) is this really beneficial?

Maybe you shouldn’t throw out your new trailer, but it looks like a good deal for expanding a fleet.

Remember that all signs point towards more CO2 fees and higher gas prices in the coming years

I'm not seeing any sign of CO2 fees increasing in the USA. If anything, they'll be federally outlawed.
Not in the next 3 year. However there are more elections coming up. And other things changing. For that matter even if the US does nothing, other countries doing something will forced changes. Petro cars are so cheap in the US (they are not exactly cheap) in large part because the design costs are amortized over so many buyers, when the rest of the world isn't buying them that drives up costs in the US.

Meanwhile I'm not the only US driver who has discovered how much cheaper a EV is, so even without CO2 fees things are changing - just slowly.

Regenerative and solar electricity is free, and regen braking additionally saves wear and tear on brake pads.

The real benefit I think is when stuff like tax codes, carbon credits and government subsidies come into play and ROI goes down significantly.

Or when the next war hits and diesel actually hits and bypasses the 2.50€/l mark.

Those are unreliable and vary at the whim of the government and their need to fill a hole in the budget. The only reliable factor here is a subsidy on the purchase price for the trailer as that can not be withdrawn after a year. Carbon credits will disappear as soon as a significant part of transport has been electrified, electricity prices are still rising, tax exemptions are temporary at best.

Sure, but that doesn't matter to the guy buying the trailer. They got a tax break, credit, whatever, and through the magic of financialization they sold that tax break for $.92 on the dollar. So they don't really care what happens. And the $.08 hedges the middle man's risk. Etc. etc.
