For all out WooFDriver activities, the Jumbo Jet is used because it it’s cargo carring capasity and comfort. Day to day use, I use the Dog Bus. I modified a Ford Transit Van be be an efficient WooF transport. Metal grate partition separate the dogs inside, similar to the Jumbo Jet. Spill proof waterdishes and fans have been installed for for the dogs comfort. After the dogs and the WooFDriver, there is only room in the front seat for a little gear or a passenger, so it can get crowded. But it gets much better milage and isn’t quite as much of an “event” to drive it down the road, or park it in a parking lot. It’s just a quick grab the dogs and go for a day’s excersie of just me and the dogs.
