that sounds like a good idea. i remember towing our 23' camper over the rockies, and it was no fun (tow vehicle was an '01 f-150 v8)

 

I wasn't pulling a trailer at the time but when driving between 0 feet elevation and 7K feet elevation I notice a huge power difference. Would this indicate a bad AFM or O2 sensor? Is this normal for the 22RE? What would be a fix for this? I'm guessing my engine is running rich because of the lack of O2 at the higher elevation but I'm not sure (I'll have to pull the plugs).

 

yeah, that sounds about right. you need a turbo-normalizer

you might benefit from an '82 supra afm, if you don't already have one

 

I was starting to think that was normal. I plan on going with the '82 Supra AFM when I do my cold air intake battery swap mod.

 

I bumped into this Toyota Guide to Towing, has weight capacities per model in part 3, state laws, different hookup education, and even lessons on how to back a boat into the water without wrecking stuff.

Sorry, don't have a clue about oxygen issues.
My truck came with a bumper ball, i'm not sure it can successfully tow a shopping cart...Well...not today for sure...

i've got a 88 22RE AUTO 4x2 pickup and want to tow my tiny 1500lbs race car on 500lbs single axle trailer. rating on the pickup is 2000lbs. a) can i tow (primarily flats) and california says anything more than 1500lbs needs to have trailer brakes. b) won't trailer brakes on a single axle just pitch the trailer down onto the hitch? i've got 1ton rear springs so pretty stiff in back.

thanks,

 

Should be just fine with 700lbs
I pulled 5000+
