There's some info at this page. I'm a rookie and haven't had to deal with that much, but I think with a 43 foot trailer you could have you tandems all the way back and not violate any kingpin to rear axle limits.
A CDL is required to drive any of the following vehicles:
A set of axles spaced close together, legally defined as more than 40 and less than 96 inches apart by the USDOT. Drivers tend to refer to the tandem axles on their trailer as just "tandems". You might hear a driver say, "I'm 400 pounds overweight on my tandems", referring to his trailer tandems, not his tractor tandems. Tractor tandems are generally just referred to as "drives" which is short for "drive axles".

Never hauled a smaller trailer, but I'm kind of surprised this didn't get covered in your orientation. Personally I'd put the question to the Schneider Trainers so that you make sure you are not only legal, but also in compliance with any company policies. Some company policies are more strict than DOT.
A department of the federal executive branch responsible for the national highways and for railroad and airline safety. It also manages Amtrak, the national railroad system, and the Coast Guard.
State and Federal DOT Officers are responsible for commercial vehicle enforcement. "The truck police" you could call them.

This is true and Schneider is big on safety. You might want to phrase it just that way: "What are the company policies on weight and length restrictions for this size tractor-trailer combination?"

The axle weights are determined by DOT. Your trailer is 43' long, your lading weight could be as high as 53k. Your goal is balance within the boundaries of the kingpin laws (if any) of the states you will be driving through. Without the benefit of a scale, I would guess your tandems should be slid completely or close to the rear of the rail. I suggest that you verify this with Schneider.

Hi all, i am starting dedicated Miller/Coors account need help. I will be driving a lightweight sleeper with a 43 ft trailer and super singles no passenger seat, and is smaller in width then a regular trailer. i can haul 53,000 lbs. My question is what are my limits on my axles is it different then a 53Ft trailer? I want to be legal. and what is the legal limit for the sliding pin on trailer?
Super Singles:
A single, wide wheel substituted for a tandem (two wheel) assembly. The main benefit of a super single is a reduction in weight and lower rolling resistance which provide better fuel economy. The disadvantage is the lack of tire redundancy (or a 'backup tire' in case of a blowout) from which tandem wheels benefit. A tire blowout is more dangerous with a super single and can not be driven on.
