Suspension options for an overweight 2nd gen?

I'm looking at getting a 2nd generation Tacoma (double cab, long bed, base model 4x4) with slide-in camper (~1,350 lbs. dry) and ARB steel bumper with a winch. I know that similar rigs are notoriously overweight, but seem to manage okay nonetheless.

This one already has an added leaf spring (or maybe a whole replacement pack) from Boise Spring Works; there's no sag in the rear, but I wasn't crazy about how it handled on a washboard gravel road when I took it for a test drive. So I'm thinking about how I can improve the suspension for both on and off-road travel with all that weight. Note that I have no plans to do any hard-core rock crawling with this rig. My off-pavement driving (what this rig is really for) is a mix of bad gravel roads (serious washboards) and easy 4x4 trails, but I need it to handle well on pavement too.

Option 1: Timbren active off-road bump stops
That would protect things from the current suspension bottoming out hard and probably improve handing in the bumps. It's also relatively inexpensive and trivial to install.

Option 2: New coil-over suspension
I like what I've read about the Old Man Emu BP-51 suspension, but that would be an expensive upgrade and I'd only want to do it if it'll make a big difference. How well would you expect that to work with my overloaded taco on trails, washboard roads, and pavement?

Option 3: Combine coil-overs and active off-road bumpstops

Option 4: Something else.

What do you think?

 

It will be an 1800+ pound pig when wet. Would strongly suggest you reconsider. But if you do decide to go that way plan on upgrading the springs and adding air bags. It might not squat but it will still handle poorly. Maybe consider a bed rail mounted set up instead...

 

Or a 3/4 ton since that's even extending past 1/2 ton range.

 

you may want a Tundra. The Tacoma isn't exactly known for its hauling abilities

 

Even for a Tundra that's a lot. Tundra's don't really have great payload although it would "handle" it significantly better than a Tacoma. Very few 1/2 ton's have the configuration to carry that weight within limits.

OP, to each their own but that's also why there's also payload capacities listed on vehicles.

 

Tacoma is already under powered when adding bumpers, winch, armor, etc.

It’ll still be underpowered with the slide in camper, especially if you go anywhere with topography.
