I think the acoustic glass makes a difference especially if traveling long distances frequently.
I prefer the Alpine system from my 1500 to the tradesman lvl 2 system.
I'd definitely spring for the 8.4, skip the nav as it leaves much to be desired. Already several years out of date and expensive to update.
The upgraded dash screen is definitely nicer than the tradesman one.
In floor bins can be added to tradesman as there is just a block off over the hole in the floor.
Quality of some interior pieces may be different too, soft vs hard plastic etc.
Remote start and remote tailgate release are not available on tradesman but purchasing the keyfob and having the dealer program can give you the capability
A significant amount of the addons can be added at a later date if you wish, it will just cost more.
