I'd love to have a little diesel though our gas powered tow does fine. As to 4x, what the Honda has is limited but I will say that over its seven years it's saved us a few times, and a couple times on roads and seasons when you wouldn't think you need it.
AS well the 4x has been totally reliable, only requiring fluid changes a few times.
It does not get Don's 28 mpg but this trip so far towing has been about 22 mpg; non towing in the 28mpg range.
though definitely not up to a Big foot 25 or Casita
