Some things I consider when sizing:
1.sticker dry weight on 5th wheel does not usually include options - it varies with manufacturer, and the year the trailer was manufactured whether they included options or not in the weight. Cannot be trusted when one is cutting it close. Weighing is the only way to go.
2.One should not exceed the TV payload weight, no matter what the sales people say. So by the time you add the hitch weight of the 5W, the bed liner, the 5W hitch, cargo, wifey and kids, dogies (i have 2) and stuff, you may have actually exceeded that as well.
3. One should also not exceed the tire rating either.
I check the following before I am satisfied
1. Tire limit
2. Axle limit
3. Payload Limit
4. GCVR limit
Looking at the pure numbers, I would reconsider the configuration.
