Towing 2 Trailers.

Just thought I would share my latest tow. This is the longest I have ever been. Around (65-70ft). A couple buddys and I went to Crawfordsville, IN to compete and watch the GNCC Iron Man competition. I pulled my camper and a trailer behind it with the forwheelers. I put it on my tow tune for the way down their. Here were my temps. EOT: 198-204(highest I saw was 207) ECT:190-200, Trans: 150-152. My EGT's stayed around 600-650. I wasn't too impressed with the way it pulled down thier. My Torque Converter kept unlocking and RPM's skyed. It cost $92 to get down their. On the way back I put it back on my Looney Tune since the EGT's werent too high. This pulled so much better. The torque converter stayed locked up the whole time(even on some of the steeper hills). Trans,EOT,ECT all stayed the same. EGT's ran around 650. 700(on hills). Is this okay? I thought I read somewhere that as long as you dont run 900 degrees sustained then your fine. Heres a pic of the load.

I think it should be illegal to pull 2 tag trailers, but it's an RV, so you can get away with anything.

I wouldn't say illegal but maybe a certification or something. Ive seen some scary people with two tag alongs. A 5er or goose with a tag isn't as bad

Illegal? No, wrong!

There should be some parameters that are consistent between the states, similar to CDL rules, but non commerce. Folks driving big busses with air brakes, or loaded beyond GVWR and GCWR...

This is a discussion for another thread for sure.

But back on track i Gibson13, I never see EGT's that low while towing. If I get below 900 on the flat I am doing well. When I am on it up the grades at altitude (above 10,000 ft) the EGT's are well into the 1200s.

The fuel mileage is not only affected by weight but by air drag and rolling friction. If you want to play with all your toys at once, it costs to get them there. You could have made 2 trips

For another photo check out lets see those toy haulers!

I believe towing two trailers is fine but the second one should be attached to a pup so its weight is not resting on the first trailer.l

Where is your egt gauge? My truck runs 8-900 unloaded. If you were able to hold 700 degrees with a looney tune while towing, I'm very curious to know where your egt probe is.

The probe is right after the turbo. My EGT's stay around 450-500 unloaded with regular stop and go driving.

There's your problem. You NEED to relocate the probe to a pre-turbo location. Post-turbo readings vary wildly and are not accurate enough to prevent engine damage.

My probe is right behind my turbo so I think i'm getting correct temps. Also this setup is not very heavy. The camper is a lightweight model(maybe 4500 lbs) and the second trailer weighs around 1200lbs with the quads.

Also I'm a bit confused. You said I should have made two trips; yet you post a pic with a double axle trailer with a boat behind your camper. Maybe I misunderstood your post or something. Are you against pulling two trailers or not?
