OK finally got around to checking the decal, total payload is 1,490 lbs, not quite what the online spec's list.
So if I have a trailer tongue weight of 350 - 400 lbs, myself and 2 sons about 575 lbs, added canopy probably 200 lbs, so total of 1,175 lbs without gear.
It adds up fast, not sure why the specs on my model showed 1819 lbs but the decal on the truck shows 1,490 lbs.
I can work with it but didn't realize I would need to keep an eye on the truck payload.
Guess I can load some of the gear in the boat including coolers, ice and cold beverages.
I've up rated the trailer so I should be OK there, it's rated for 5200 lbs and the Stabicraft 2050 shows a tow weight of 3,300 lbs, so I shouldn't be above 4,000 lbs loaded.
I'll get it on a truck scale once it's all setup and see where I'm at.
David.
