Your truck has air brakes not Hydraulic, I just looked at your pictures and can see the air guage on the dash.

Every one of these trucks I have ever seen has air brakes. Interesting.

Hydraulic brakes?

It's not just the airing down, it's how you drive. Straight you're pretty safe but hard turns or off camber and you could be in trouble. The tire manufacturer will have a table with weight, tire pressure and max speed.

I regularly aired down to 70psi for comfort and 40 psi for soft stuff with the 315 22.5 80. That tire is too narrow. Sure you're not going to go down to 10 psi with it!

Before you go to the r20s, do you plan South America? R20s are unavailable in South America. Strange but true. A 365 or 395 22.5 is a better choice for 99% of your driving.

The wheel base is fine. Extending it is a huge mistake. Our 917 had a shorter wheelbase and an 18' box. Incredibly maneuverable and drove great!

I regularly dropped our 315 80 22.5s to 60 psi, never an issue. 9400kg.

It would be nice to fill the horrible gap between 3rd and 4th. I Could never understand MBs choice of a 5 speed for these trucks.

154 hp, It will be slow!

Gov of Canada website, you'll have to dig.

Anything new. Cars start here all winter, it is very rare to plug anything in. Ontario Canada.

The exhaust brake is probably quite effective on a bare chassis. On a fully built out 917 it will require slow descents at high revs to hold you back. I am guessing it is the 12' wheelbase. Our MB 917 had a 12' wheelbase with an 18' habitat. Very stable with a great turning circle.

Jabsco or Shurflo 12V water pump. Simple. We had an Isotemp hwt in our truck. The first one lasted more than 20 years. The second is more than 10 years old. Great product.

I had 315 80 22.5 tires on our MB917 At 9400kgs they are not wide enough. Go to at least 365's. As for a specific tire you want an "all position" tire. Look at tires designed for construction and logging vehicles.
