Another easier solution is to install a Lloyd Mat carpet. It will reduce heat, and noise, and made my DW happy in our old E-450. I already have new one sitting here for when our new 2500TS arrives.
You can get one from AutoAnything. See Here
. Just enter E-450 with the Select Vehicle Options and you'll see the one piece one I ordered. The Lloyd's Part Number on my order is: UM4 \ 3302280.
Note: When Ford ended Econoline production in 2014, except for the incomplete chassis, most online ordering systems also stopped at that year. I always claim to be a 2014 to spoof the system when ordering trim
parts like carpet. For drive line parts I use the real year...

It is better to have too much truck than to have too much trailer.
