It is more of a concern for camper owners than owners of other types of vehicles, as Cali’s (in particular) hold their value SO well because they have a 30 (40?) year plus life.
If that life was to to be cut much shorter due to changes in law, fuel availability, social acceptance, then residual values would fall.
As has been said, there is currently no electric alternative (and they have plenty to worry about too). I’ve warned that owning the first electric Cali will look like a Betamax video after only a few years, as they will improve at a rapid rate....so waiting and buying a first electric Cali might not be wise either.
I do think however that when the first electric Cali lands, existing Cali residuals will take a hit...nothing too major but hurtful enough for some ‘income poor / asset rich’ owners like me. If that is true, the newest diesel Cali’s would probably be hit the worst.
This logic was (only) a part of my decision to run an older Cali. If you think my hypothesis is true, then why not buy a 2010 140hp Cali now, and get 95% of the fun with much lower outlay and lower risk of being hit by a fall in residuals?
