Yes. That is a big board. This is the same for me.
I use this board and case:
https://pedaltrain.com/products/novo-32-with-wheeled-tour-case
In the specifications, it says
Novo 32 Pedal Board
- Dimensions: 32 in x 14.5 in x 3.5 in (81.2 cm x 36.8 cm x 8.9 cm)
- Weight: 5.5 lbs (2.52 kg)
Tour Case
- Exterior Dimensions: 37 in x 18 in x 9.5 in (93.9 cm x 45.7 cm x 24.1 cm)
- Interior Dimensions: 15 in x 33 in x 6.5 in (38.1 cm x 83.8 cm x 16.5 cm)
- Weight: 26 lbs (11.8 kg)
The case is 37 x 18 x 9.5 inches and
weighs 26 pounds empty. Add 5.5 pounds for the board, which brings it to 31.5 pounds before we even add velcro or a single pedal. I have 2 Fractal Audio EV-1 pedals on it, each weighing I estimate my loaded board is around 3.7 pounds. The MMGT10 weighs 6 pounds, and I have a few other items on the board that probably add a total of 3-4 additional pounds.
So that's 45+ pounds on my 32 inch board in the flight case. It's a good thing that case has wheels

I can fit that case onto the back seat of a regular car, but it's (1) big, (2) heavy, and (3) a flight case with lots of upholstery-hostile surfaces. For local gigs, I load that thing in the back of my truck and off I go. For touring, I load that thing in the back of somebody else's truck and off they go.
As I noted before, a 43 inch board is nearly 1/3 larger. I know the Temple boards don't weigh exactly the same per square inch, but just taking a rough guess, the loaded board alone would be 30+ pounds. Add another 30+ for the flight case. There is a lot of benefit to having everything fully set up on a big board, with all the wiring fully ready to go. But... I can tell you from my experience as a touring musician, almost everyone I know has either rack mounted their pedals, or broken their big pedalboards up into a few modular boards that quickly interconnect. It lets you angle them, rather than having a long single surface to cover, and makes cartage (gear transportation) MUCH more affordable, as the individual units are both smaller and lighter.
You indicated that you have an FM3 sized Temple board on the way. Another possible approach would be to have most (or all) of the other pedals on another board, and use a MIDI / remote loop switcher to engage them. That would let you arrange them as tiers / layers, rather than needing all the square footage for them to be on the same surface. You would mainly interact with the controller, rather than the pedals, so it's less tapdancing - AND an intelligent router would allow you to change the order of the pedals.
