"The grass is always greener....."!!
I have a Hurricane 34E with the fuel door on the driver's side of the coach. However, I can clearly recall telling myself that it would be great to have had the fuel door in the center rear of the coach, so that I can fuel at any pump.
As it is, the coach is 35' long. But, when pulling a toad the rig is about 54' long. So, I already must carefully consider my approach to the pumps when fueling, but I am ALWAYS limited to the driver's side.
It would be so nice if I could pump on either side!!
