New Suspension Lift with 450 lbs in the bed?

I've hit 115k on my 2015 and have decided to go from OEM to a new suspension system. I want to drive my 2015 for another 115K and am debating between Kings (thinking with Dakar leafs) or Icon (can't decide between Stage 6 with Dakar or OME leafs or going for Stage 10). My bed has a camper, RTT, and will have a storage system, bringing it to an additional 450-600 lbs at all times. I'm hoping to add 2.5-3" from stock and have a reliable suspension for the next 100k-- about 10k of which I imagine will be on dirt.

Suggestions welcome.

 

Check out Deaver Stage III leaf I packs. I like mine they’re good for around 1000 pounds I believe and they’re a progressive pack so ride really well also

 

OME Dakars in the heavy configuration has worked well with rigs that ended up with load in the rear end. Icons were good also but the setup was a pain. I've heard great things from the deaver Expo packs that are rated for the highest capacity.

 

I am also rock'n Deaver Stage 3 on my '15. I carry 800lbs+ all the time. Love the ride.

 

Check out the crippled angler as another option for leaf springs, great price too. I have had them for about a month they ride great with my set up.

 

i have dakar hds. Id listen to Casper and the rest that are saying deaver. My dakars squeak like hell, and will be switching to deaver in the long run myself.
