Yes, the E-450 frame is a little thicker on Cutaway Chassis, but on Stripped Chassis (used to build Axis/Vegas), both E-350 and E-450 use same thickness. Regardless, weight difference due to chassis thickness that would affect fuel economy is very minor.

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.
