I don't know what they called the old Trans Vans (from Champion I believe), but some of those were pretty long. I was pretty hot to buy one of those until I found the Trail Lites about a year and a half ago.
I must say that, while I have been quick to point out deficiencies, I have really enjoyed my B+ over the past year. Not only has it fit very well in my professional work, but it has provided me access to my work weeks earlier than would have been possible if I had to travel to a fixed office or use a regular vehicle to see my clients. I have been able to briefly rest, fix meals, relieve myself, and drive easily to the extent that I was at work (at about 75 - 80% of my pre-operation efficiency) within two weeks of major surgery.
Now, a little over a month later, I am back close to my regular routine, even though I am still recovering from the surgery. I can not imagine a better tool for my work in this (or my regular work environment)situation.
