There is a LOT of variance in trailers. I have two small flat trailers with the utility type tires/wheels (12", I think) rather than larger (13"+) car style wheels. Pulling empty with either an imiev or a Tesla, you hardly notice an impact on range, under 5%. Loaded with ~1000 pounds that sticks up ~2', the impact may be close to 10%.
Still, that ~5% may well be enough to wipe out any benefit from having PV panels.
I also have a "small" teardrop camping trailer that costs 25-30% when pulled by a Tesla.
