Like larsdennert I too have a R1S (quad moter, he has dual motor and Max battery) - and we both have lifted GX470s. oldstick's opinion is certainly valid - in some situations. And that's the real issue here - vehicles have multiple missions...commuter, travel, recreation, utility, towing, etc. - and BEVs are not optimal across all of those. And as with anything that is...well, hyped...there are some over compensations. Look at Norway - vast majority of NEW vehicles are BEV but they still under 1/2 of vehicles on their roads. They are now refocusing on reducing the number of vehicles.
Meanwhile, some of us are fortunate to be able to have multiple vehicles - others must/choose to make do with one vehicle (or even vehicle sharing).
Everything is a compromise - TMs are the epitome of that. If all travel trailers cost the same, had the same towing/maintenance/cost/storage characteristics, I suspect most folks would be rocking 30' Airstreams.
So a TM represents an optimization - one that aligns with the owners and prospective owners on this forum. BEVs - and Rivians in particular - are the same. Where it gets truly interesting is when there's a further optimization of BEV + Travel Trailer - and that's where folks like larsdennert are pushing the envelope - for which we all benefit.
