First Thread! Let me start by saying thanks to everyone in the yotatech community for all the contributions you've made over the years; I've lurked here for years, benefitting from this mass of info.
I grew up on 80s model Toyota's and currently own a 1983 Sunrader (purchased in 2012 with 34800 original miles, and have put another 20k traveling all over the US) and a cherry 1984 Toyota XtraCab Solid Axle 4x4. The truck has OME heavy suspension lift, rebuilt axles, de-smog, ARB front bumper, Warn M8000, and rides on 31 BFGs at factory gearing (4.10) with the factory 5-speed manual.
I imagine right about now you're thinking "sweet, nice ride, welcome to Yotatech, etc.," well...
Let the flaming begin: So I've acquired a 1986 Bigfoot 5th wheel weighing in at 2700lbs with a gooseneck tongue weight of 550lbs, and it is equipped with trailer brakes
. It will only see use within 100-150 miles of the house. My plan is to have a Fab/trailer shop install a quality gooseneck hitch with a hide-a-hitch mounted to the frame below the bed, as well as a quality brake controller.
I will be doing the FJ Disc/caliper/dual diaphragm booster upgrade upfront, swapping the low-milage 22r from the Sunrader, and may do a new Marlin W56, as well as swap in 4.88 diffs.
I'm not concerned with the 22r's ability to handle this, as the Sunrader is 6800+ lbs gross on a factory 2wd drivetrain (save for the 1-ton factory rear axle) and has been coast to coast (slow and steady) through all manner of mountain passes, BLM back desert roads, and nearly every National Park in the lower 48.
I know there are a LOT of members who will now think "this is bat˟˟˟˟˟ crazy, this guy is nuts, how could you do that to that 84!" Etc... Know that this is a compromise [wife] in order to keep my beloved 84, the alternative would be sell it and buy a quad-cab Tacoma or Tundra and I just can't do that. So, I'm starting this thread to document the process, as there was absolutely no information out there on anyone doing this to an 80s pickup - closest I came were people hauling the same camper with '03 and '06 Tacomas and they reported no issues, but offered very little detail.
