Might as get this started, so all the related info isn't buried in the less see you trucks thread.. I'll be shifting throw that thread to cross post over here
Due to current ELD mandate of needing electronic logs in the truck by 12/17/17 for vehicles 2000 newer.. and by that time my current mule 07.5 LMM will be pushing 500,000 miles.
Been on the fence for a while either to repower a 90s 3500HD or jump into a full on MD truck.
On 11/7/16 I picked up a 99 fl60 extended cab, with a dt466 engine, Eaton 9sp transmission, 8/15k axles 3.73 gears, HYD brakes, air ride cab, seats and suspension.. 22.5 rims mismatched tires LP up front and 11r22.5 out back.
Come to find out OEM was a 3116 cat, with a 6sp. One of the previous owners swapped a dt466 in.. including an international dash cluster.... Slid a cuttoff chassis on the truck...the dt466 looks natural in the frame, so I'm Wondering if the PO stuck the cab, hood, bumper, then slid the rear frame over a international frame... WB now is pushing 190".. I think the original is 150-160 range
General end goal is something along the following
General idea where I'm going with this
Weight,
drops frame/truck 4-5"
The GN pin height is maxed out about 38" vertically.. your avg 22.5 is 40-43" tall, trucks frame is 41".. lower the bags too much throws ujoints out and messes up ride quality
225 and 245/70/19.5 are extremely common with class 4/5/6 trucks. Ford 450/550, dodge 4500/5500 and the like chassis trucks, 50/50 on class 6 trucks 650/6500
While they make 245-255/70/22.5 which is mainly used on single/double drop trailer and like.. I have limited dedicated steer/drive tire options compared to 225/70/19.5 and 245/19.5
Another aspect is weight capacity of tire compared to what I'm running.. I have similar issue with the 19.5 and my LMM.. even at the lowest weight rating of 3600(dual)lbs I have 21000lbs of tires on a truck that rarely weighs more than. 13,000lbs, rear end skips like a Mg in bobtail fashion, any slick conditions increases chances of get squirrelly while empty
Same principle applies with 22.5, 6 tires at 5-6000lbs a piece, 30-36k, on a truck that won't weight more than 23k.
You can only let soon much air out to soften ride quality before you risks over heating the tire due to under inflation

General idea where I'm going with this
Reason/reasoning to swap back to OEM 19.5ssize engine, completely de emissions, @400/1200- 450/1500 hp/tq with engine retarder
The LMM is ~400/800 at tires so.. ~450/900-950 crank ish extra 3-400tq would definitely run
9/13sp Eaton double OD
air suspension F/R with full manual dump and over inflate capability on both axles
air disc(meritor pan 19, 14.8" disc brakes),
245/70/19.5" H load
9k/17k axles, (lockable diff)
26k/54k gvwr/gcvwr
34-36" top frame height, ( preferred 32" but doubt I'll have enough up travel between bottom of frame and top of axle, it be less than 3" up travel with 10 5/8" common frame size, on rough measurements and 5" axle tube)
170" WB.
100-150 gallons onboard
10 5/8" frame
Body
42" flat top style sleeper, with a proportionately widened/lengthened/raised, pickup truck style cab, keeping the truck under 84" tall preferred less than 78"
Obviously full power windows/locks/seats/mirrors
Heat/cooled seats
Heated mirrors
Keyless entry with remote start
AC/heat with cabin filters
Full HUD display, plus DIC with mechanical gauges
Weight,
drops frame/truck 4-5"
