YW!!!
How much does the family weigh total? Remember the kids unless already mostly grown, will only weigh more with time, decreasing you payload! Lol
With about 1500lbs payload, that should be ok for a smaller bh model. How many kids?
Do you have a topper or anything added to the truck?
The Jayco Jay Flight 26 BH may be a fairly good match for your truck, pending the number of kids you have. Estimated 6,000lbs loaded, roughly 800lbs tw. Leave about 700lbs for the wdh, family, and coolers.... The Jayco Jay Flight 27 BH would be a little heavier, but with a slide which does add some room inside. But may be marginal depending on the family weight. Estimated 7,200lbs loaded, maybe 900-950lbs tw????
I know what you mean about learning about the payload part of towing!!! We had a '10 Chevy 1500 CCSB 5.3,6spd,3.42 truck rated for towing 9,500lbs or so!!! But with about 1,550lb payload also, that was quickly gone even though we are not a heavy family weight wise. Truck topper, firewood, coolers, bikes, etc all added up to being a it 200lbs over the trucks gvwr!!!! Live and learn.... Never had a Ln issue power wise with the drivetrain, just needed a little more payload capacity!!! We ended up doing ok trade in wise when we stepped up to our current truck, '13 Chevy 2500HD CCSB.
Check every so often on trading the truck in. See what the current offers are on a 2500 or 3500. Never know what can happen!!! Could end up doing what we did, bought nearly the exact same truck option for option, and color! Difference between the two: Was Imperial Blue, now we have Blue Topaz. The only other option differences I can think of is we now have the factory brake controller (works awesome!!!), power pedals (didn't care!), back up sensors, and a rear window defrost.
Do you have the factory brake controller? If not the Prodigy P2 and P3 are highly regarded!!!
Once you get the trailer it is only a madness of doing mods at that point!!! Lol Gotta make the trailer more useful for you!!!
