Greetings -- I've been an occasional wallflower on this forum for a while now, I always find useful stuff on here! Now I am a bit overwhelmed and thought I'd reach out for some feedback. I have a 2016 Nissan Frontier with a 2001 FWC Eagle and am looking to beef up our tires and rear suspension. FWC has recommended the Timbren SES for the rear suspension and one of three tire options, all E-rated: BFG KO2 all-terrain, Toyo Open Country (although they said these would be louder, lower mileage), and the Goodyear Wrangler. My dad has also recommended the Supersprings to me for the rear suspension.
We do a lot of highway miles since every summer we do a camping road trip between OR and WY. Also a fair amount of dirt/forest service/BLM roads and a bit of 4WD roads but limited these days now that I have a toddler. Camper is on the truck between April-ish and November-ish.
I try to go to Les Schwab when I can since they have such good warranty/customer service and lots of locations for repairs where we often travel, and they recommended their Backcountry 10-ply tire instead of the ones listed above (I guess they don't carry those other ones?)
Long story short my questions are these:
1) Does anyone have experience with the Timbren SES and/or Superspring rear suspension upgrade kits? Pros/cons of each? I am pretty sure I have decided that I want this option rather than an added leaf or air bag based on our usage.
2) Can anyone provide a comparison between the Les Schwab's Backcountry tire vs. the BFG KO2 or Toyo Wrangler?
