Axle weights and traction


Ethos

Recommended Posts

I bought a rescue truck that I am converting to an RV.

Firetruck chassis with ambulance rear.  Being a firetruck chassis, the engine extends over the front axle a bit.

Traction on icy conditions is very poor.  Tires are in good condition.

Steer axle weight is 11,500.  Drive axle weight is 7060.

Gvwr is 26000 lbs.

Will adding some weight to the rear make much of a difference?  

I'm new to RVing and new to medium duty trucks.

All advice is welcome.

Congrats, please post your progress. Many have thought about it, but only a few have actually done. 

Traction on Ice is never good. My plan is to stay put unless something really important changes said plan. 

Be sure to check the dates on the tires. They may look really good, but maybe as old as the rig depending on how many miles are on it. 

My initial thoughts this morning.

As you convert it to an RV, you'll be adding a significant amount of weight. That will help improve both the ride and traction. Putting some of your heavier items as far back as possible will help transfer some of that weight toward the rear and help balance out your axle weights. Jay

Put your auxiliary freshwater tank of your generator fuel tank behind the rear axle. That is a good way to gain some weight in a hurry.

plan your weight right. as you only have 1000 pounds MAX to play with on that front axle. dot max weight is 12,500 pounds. and 500 pounds are a "given" extra as long as the rear is not up to it's max weight. not sure what the max weight is for that class, check first then build up.

Well, no, max DOT weight on a steer axle is 19,000#, provided the rim and tire are wide enough, and the axle is rated for it.

Much heavier than i thought they were. Converting it to RV puts you over the magic 26,000 lb mark. Im 18,000 loaded with clothing and food in the fridge. Without trailer

 

 

 

The magic 26,000 pound weight is not usually a problem with RV's.  Many RV's exceed that, sometimes by a lot but do not require a CDL.

Some states, like TX, do require a non-CDL class B license for over 26K RV though.

That would be a Class B for motor homes over 26,001 lbs. and a Class A Non-Commercial Exempt for towable combinations where the trailer is over 10,000 lbs. and the combination GVWR is over 26,001 lbs.
