No I'm saying the full 700 pounds has to be subtracted from the 10k pounds max before it requires logging and all the problems that come with it.
OK. While we're at it: It has nothing to do with the actual load. It has to do with the manufacturer's GVWR. If the COMBINED GVWR is over 10K, you have to log and so on EVEN WHEN YOUR VEHICLES ARE EMPTY OR LIGHTLY LOADED. Fun, ain't it?
Example: My van has a plate on the door that says my gross vehicle weight is 8,600 lbs. Empty, but with full gas tank, me and my personal effects, it's about 5,670. Add a trailer with a builder's plate that says its gross weight is 1,700 lbs-- but with only your stuff in it the thing actually weighs a little under a thousand. Guess what, I gotta scale in many states, I'm subject to logging, have to have the DOT physical and all the rest of it empty or loaded. Because 8,600 and 1,700 comes to 10,300 lbs.
Now, my van is a 2500 series van. Many in our business recommend getting a 3500 series van because your weight capacity is higher. A van that has a builders plate that shows 9,500 GVW gives you plenty of weight capacity inside the van--- but not much left over for a trailer. Most every pop-up camper trailer on the market will exceed that.
That trailer looks like a lot of extra work for little if any reward--- spending money on a motel room instead looks better and better.
Fun fact: What I just said about DOT-- forget about while you're on vacation. You're on your own time, not doing commercial, hook up your trailer and have fun. But, the instant you come back to work and run this as a commercial vehicle, all the DOT stuff comes into play.
