2021 Ford E450 with built in TPMS
Hi Kent;   you typed   "Built in TPMS systems are expensive to repair when they fail and will require shop time and at least a couple of hundred $ or more to replace."            Well sounds like you have had a bad experience with factory TPMS.  I only have two cars with that right now. The 2007 with 145k miles still has two wheels with the original batteries-in-wheel transmitters and still work fine. Just replaced three sensors at my last tire change last year, so that was 13 years of use. About $70 per wheel. The tires were a lot more.
    I've heard that if you buy a truck with built in TPMS, you can get more sensors for a trailer that will work with the dash and add them there.   If not you could get an add-on TPMS for the towed vehicle, and if the Ford dash portion were to quit, you could expand that add-on to include all of the tires.  IMHO if the dash quits, usually most of it quits, affecting many other systems as well.
    Depending on how Ford implemented the supplied TPMS for 2021, you may be back to flexible extension hoses.  It looks to me that Lazy Daze is only ordering the  'premium' chassis.    RonB

The built-in TPMS I have seen do not identify individual tires, their pressures or temperatures.  Are the new ones better? 

My 12 year old system shows pressures on each individual tire, including my TOAD.  The built in TPMS on my 2011 TOAD shows a low pressure warning light on the dash, but does not tell me which tire it is.

"The built-in TPMS I have seen do not identify individual tires, their pressures or temperatures."

The built-in TPMS in my 2019 Subaru Outback identifies individual tire pressures, but not temperatures. So did the built-in TPMSs in my 2017 Ford F-150 and 2019 F-250 pickups.

Hi Ken, my 13 year old Lexus shows 5 pressures in sequence. When I got the car, I let air out of each tire to identify which tire was which on the display. They don't report temperature, but I often can see which two are in the sun when parked. As I drive;  faster will result in higher pressures, from 35 cold to 40+ when hot. Four people vs. just the driver will heat the tires differently. Normally the front tires increase most.
    My newer 2015 Lexus, displays an outline of the car, center dash, with each tires pressure. Both cars also display the spare also. Once on a cold day, the car alarmed for low pressure on the spare. I do have full service spares, but with standard rims. I may try to switch out the spare for a front tire someday, to see if the car detects the pressure transmitter ID along with location. My suspicion is the setup is made by a tire technician. I do know that presently, the tire position  indicated on the dash, does correspond with the location of the tire on the car.      RonB
