Canopy on 79 series or just get a 100 series, pros and cons of each

Hi, I ve got a 79 series cruiser and was thinking making a canopy for it. I am also in two minds whether to sell it and spend a bit more money on a well equiped 100 series. I ve had cruiser tray backs before and they arn't that comforatble or nice to drive, but tough.
What are the pros and cons of each vehicle, 79 series with a canopy, dual batt, or 100 series with a bit of fruit, _Affordable_Storage_Drawers.aspx, dual bat, etc
We like to get away a bit in the Pilbara, so long trips are on the agenda....I also have a wife that likes some comfort as most do!!!
Thanks for taking the time to reply
