I have 2 short/low 1 long/low and 1long/tall. They are awsome trucks but not for everyone. I had enough of the POS full size vans with gas v-8s getting 8-10mpg. Even with the ladder racks on top we are in the 20 range. Be careful with maintenance and they will last us 10 years and 500,000. If I had unlimited funds all 8 of my service vans would be sprinters.
Some day soon we will all get small deisel engines that run on the smell of your shop rag but for now we'll deal with the heavy vehicles.
How about a 650 dual sport deisel that gets 100mpg or better.
