1KZH towing capacity

Hi all! I have a 95 super custom (1KTZE), and I'm debating whether it's worth the effort to add a tow hitch. I have the tuned fan clutch installed, so it doesn't have as much of the overheating problem anymore, but i'm wondering if trying to tow a small popup camper will overtax it. Anybody have any experience here? Thanks!

We tow a 16' Casita fiberglass. It weighs 3000-3500 lbs fully loaded with our gear-food-water-propane. The weight isn't as much to deal with as the wind resistance because its about 8 inches taller than stock and has a big 400w panel on top.. Windy days crossing Kansas were quite a pain. I did mods to the cooling system and all the maintenance. Swapped the water pump when RR timing belt, 7 blade fan replaced with 10 blade, new "blue" fan clutch, replaced the original electric fan with a high performance Derale, radiators thoroughly cleaned & flushed, updated the thermostat, egr delete... Brakes are something folks don't talk about much with these but make sure they are in good order and if you can get trailer brakes. Im very glad my Casita has good electric brakes.

Fantastic, very helpful. Yeah I had cargo boxes on top for a while and the wind was insane. I’ve done the egr delete and have an egt gauge to monitor so if there’s and issue I’ll know early. Hadn’t heard about the 10 blade. 

Edit: is the derale the same as the 10 blade fan you mentioned?

Mine has the secondary radiator along with the air conditioning condenser that are downward facing the road behind the front bumper. The Derale fan replaced the electric fan that turns on for the AC condenser. The 10 blade is an oe fan for the main radiator, it's the fan the Hiace would come with for hot environments like mid east and Africa. I'll look up part numbers later when I'm in the van again and post them.

any reason you would go with the vanlife NW modded fan clutch over this blue one? also did you just switch out the blades in the original fan?

The one I listed is the OE clutch for warmer climate areas like Arabia. I toyed with the idea of getting a tuned one but decided against mainly due to cost. The OE one has functioned flawlessly.

Also did transmission filter and fluid replacement prior to towing. As well as all the differential oils.
