Many RVs have a ladder at the back. Many people attach their tote tanks there or put them in the truck bed. I have an Airstream, so no back ladder, so size really did matter. I choose this model because it would fit behind the the propane tank area. Also, the 15 gallon size allows the unit to be hitched to the tow vehicle.One suggestion for the manufacture if you're reading this: How about making a clear strip in the body of the tank to gauge the liquid quantity???
