The Ford Edge while heavy in comparison to a Sidekick or Vitara is towable four down and with an automatic.
Suzi's are not easy to work on, they are small and there is ten pounds of stuff in every five pound capacity space. Good news is they are uber reliable.
We currently have four vehicles, the Winnie, the Sidekick for towing and two DD's an explorer and a F-150(beater truck) The Explorer has 265K miles and needs to be replaced. DW seems to like the Edge and it will replace the Explorer and the Suzi, with a net savings on insurance.
For ten or twelve weeks of towing the reduction in RV fuel economy towing the Edge is negligible over towing the Suzi. For us the swap is simple, a nice new Edge, replaces the Explorer that is worn out and the Suzi which is a GAS HOG and not very sophisticated.
