Well, as I am as far away from trendy as anyone can be, here's my prediction of what will not happen:
Small RVs (under 24 ft); simple interiors with a dinette, unpretentious bed (not taking up the bulk of the space, bathroom sink IN the bathroom; no TVs, microwaves, generators; strong battery power; appliances running on dual or propane - not electric only; usb connecting to 12 volt directly; neutral solid upholstery - no more prints.
When asked about camping, no responses about RV Parks, glamping, etc. will be made. Camping will be camping - no hookups, no social activities, no playgrounds, just the outdoors. RV Parks will be referred to as Parking. Glamping will be referred to as "that stupid thing people use to do and try to call camping".
