The “standard” fuel tank on E-450 is 55 gallons, whereas the standard on E-350 is 40 gallons. However, every E-350 motorhome I’ve ever seen had the optional 55 gallon tank, with exception of the single rear wheel E-350 chassis that only comes with the 40 gallon standard tank. The little Thor Chateau 19G based on SRW E-350 is an example of this exception. Not many motorhomes have been built on lighter SRW chassis due to limited GVWR; so by far most have 55-gallon fuel tanks.

the frame is taller on the e450's...like 2'' taller the length of the chassis...
