Truthfully, no. I'd love to have long-haul truck seats with air suspension, but the pricing is, for us, out of reach.
We've done so many other upgrades (floor, replaced dinette booth with credenza & table, induction cooktop, residential fridge, recliners, Trav'ler satellite dish and more) we need to take a financial breather.
In any case, we just turned 101,700 miles and it's only on the worst long-haul days over 350 miles/6-7 hours that the seat becomes really bothersome. Not too many of those--we try to avoid drives over 5 hours and even those we usually share. But new seats will be next up.
