DCLB FTW... 6' bed is so much better. DCSB are better wheelbase for wheeling, but the DCLB is plenty capable, and i only wheel on the way to the river or a campspot anymore. LOVE the tacoma except i do get shitty mileage. Lots of weight with topper,bumper, and sliders. (then theres the boating gear...)
I also have a big family- 4 girls,(3 stepdaughters and a 3.5 yr old daughter) so 3 in the back seat including a toddlers car seat sometimes, and wife up front. they def. fit but its tight....
My input: the Tacoma automatic Transmission is awesome. fricking solid, 5 speed sealed tranny, (no dipstick) you can downshift and drive it pretty much like a manual if you want to (i am still used to downshifting to save my brakes.) DCLB TRD sport is only available with Auto tranny, and LSD rear. the LSD is actually better for snow driving and everyday usage. (e locker better if you are stuck. ) i have yet to get stuck....
I have a snugtop hi-liner. It is a very solid top of the line topper. I am really happy with it. came from the factory with yakima racks. you cant put an external steel rack with snugtops because they have a slight overhang to hide the lip of the bed. I sprung for all the goodies like side windoors, and it is a worthy investment in the truck.
I also upgraded my suspension to accommodate the heavy loads, as the stock toyota leafs are stupid weak. I did Old Man Emu Dakar Leafsprings, and upgraded shocks Coils and upper control arms.If you are going there, i highly recommend OME products. they are designed/built by ARB in australia, for expedition (loaded with weight) style use rather then flexi- crawling type use.
You can do some research here: www.tacomaworld.com.
it is a really good resource for used parts , DIY fixes , mods, upgrades and all kinds of internet shenanigans. It's literally the buzz for Taco-heads.... dont say i didnt warn you..
Check out the 'mods and tutorials' header for all kinds of cheap and free fixes and mods. also the classified section for parts and trucks. people are upgrading parts like we go through kayaks, and sell em cheap... I got most of my lift, ARB bumper and other stuff used.... O and there are group buys for discounts on new stuff.
I would be very interested in the Hilux someday, but i am set til then....
Last thought, if wasnt worried about the big fam, i would absolutely go for the access cab standard (6') bed. best of both worlds then, and you can get it with the TRD offroad (E locker) and manual transmission.
