For now sticking with - 265/70/17 Toyo at2 .quite- nice ride on the freeway. Whereing good 15000 so far. I will move up to a 285 next time. Plenty of room.
Ref,
I am building the same van as you have, what size tires are you running?
Any advice is welcome, it's at SMB in Fresno. Just got it painted, ready for the build out, then off to Agile for the RIP KIT.
Tell me about the rear springs please. Did you consider Deavers? How much did the AO springs lift the saggy rear end?
Did you go with the high end Fox steering damper? Is it noticeable?
I still have the stock suspension on my EB350 Quigley 1995, but I had Super Springs installed which brought the rear end up to level with the front. https://www.supersprings.com/
