1st gen Tacoma suspension upgrade options for hauling max payload (truck camper)

I have a 1999 Tacoma with 230,000 miles and a truck camper. The camper pretty much bottoms out the suspension and the ride is poor. I have done a lot of research into suspension upgrades but am stuck and looking for help form the community. The most common upgrade I see are firestone airbags (d). However my concern is the truck suspension is old and worn and will underperform with any option, including airbags (See photos for how low its sits with camper installed). My gut says to install a new set of Old Man Dakar leafs (f), or better yet a full suspension overhaul (g). However I don’t know how well these leafs will handle the camper weight - and my fear is I’ll install new leafs only to have them still bottom out. Then, will airbags be out the question because of the increased lift.

Truck
- 1999 Toyota Tacoma sr5, 4x4, 230,000 miles
- tires have aggressive offroad tread, but are otherwise stock size.
- Northstar mc600 slide in camper

Suspension Upgrade Requirements
- Eliminate sag and “level load” at max payload (~1500lbs)
- Improve handling performance, reduce sway, roll, etc.
- Lift is OK but not required
- One solution is ideal, but a combo would be OK

h. If there are other leaf options better suited for heavy payloads I’m open to more options!

Thanks!

Not the best photos, but you can see how compressed the leafs are under the weight of the camper.

 

Option G is really only if you're looking to lift the entire truck. Your last leaf springs are shot to hell and need replacing. I'd go with some Dakars or All-Pro leaf springs with either Bilstein or OME shocks to keep the cost low. Odds are the front is shot too so you might want to go with a full suspension upgrade on all four corners

 

Thanks for the advice Mr Biscuits! I'm looking at this kit from All Pro: (the Pro kit with u-bolt flip). The front is adjustable from 0-3" lift but the rear looks fixed at 3". I would also get the kit with the Expedition leafs which are designed for heavy loads. Additionally I'm considering adding Timbern bump stops: .

I suspect that with these 2 upgrades I will not need airbags.
