Nice setup! I'm looking to get a toy hauler in that same weight/length range, so it's nice to see yours and see how it works.
Rather than guessing at the weights, I'd suggest you go to a local CAT scale (www.catscale.com) and pay the modest fee to weigh your whole setup, as well as just the truck. With 2 or 3 measurements, you can get all the info you need (trailer weight, tongue weight, truck weight, etc). I think it's $12 for the first weight, and $2 for each subsequent weight. Don't quote me on those prices, though. Also, I'd suggest reading up a bit on what you need to measure and how, and then you'll be able to have accurate details of the weight of your setup.
Thanks! I actually did use a CAT Scale on my way home from our last trip. There is an app you can download so you can get the info and pay without having to go inside. The weighing results are sent to your phone and to your e-mail. Or you can still go inside to get the paper results. The cost for each weighing is $12. From what I read, the $2 fee for subsequent weighs is when you're trying to weigh the same rig setup, just adjusting the weight in the truck/trailer (18 wheelers). In other words, if you're trying to max out to the truck/trailer limit, you can weigh the rig. Then you can add more or less depending on your need and then go re-weigh to see if you get the desired results. There's also a time limit on the re-weighs, they have to be within a certain time window from the initial weighing.
The results provided the weight on the steer axle, the drive axle, and the trailer axles (one weight for both trailer axles). I did this on the way home with the wife. No way would she have let me disconnect the trailer in the Love's parking lot and then go weigh the Raptor without the trailer. I think that is about the only way to get an approximation of the tongue weight. So I had to be content with just the total rig weights. Happy wife, happy life!!
