Well as an update, I attempted to meet up with the ROF group for the
RimRocker run in Colorado and Utah but had a setback. I wasn't paying close attention to tongue weight and the capacity of my rear springs. In the pic below that I previously posted, both trailer and LC were unloaded:
As you can plainly see from the gap above the tire in the rear wheel well, it's already hunkered down. Loaded up for the trip and weighed in at the local truck scales the trailer was 2000 lbs and rig was 7500 lbs, including tongue weight. I don't have any pics of that but, IIRC it didn't
seem any worse. And while towing it the perfomance and handling was pretty much what I expected. So, I set out for meeting the group. I have a 24 gallon LRA aux fuel tank mounted in the OEM spare tire location, which adds to the droop, somewhat. This aux tank transfers fuel into the main tank by a dash mounted switch/gauge:
There's an amber LED above the switch to indicate pumping or transfer is in progress. A sequence of 4 green LED's tell the level - full, 3/4, 1/2, 1/4 and a red LED at the bottom to indicate empty. As your main tank gauge goes down you start up the transfer. I choose to do it in 1/4 tank intervals. It's not quick, but it's effective. You watch the main gauge and the LED's to monitor the progress. Well, I was doing my second transfer between Burns, OR and Winnemucca, NV, but it appeared there was no progress after what I thought was reasonable amount of time. So I pull over. There's 2 other checks you can make to be sure that it's working. 1st is to listen for the fuel pump (toka-toka-toka) sound. 2nd is to open the fuel cap to hear the gurgle of fuel being pumped into the main tank. Well I could hear the fuel pump (sometimes you can hear it while driving - depending on road noise - wind - surface). Ok, now to open the fuel cap. The 80 fuel cap takes several turns to remove, so as I'm unscrewing it I hear the sound of escaping pressure. Unbeknownst to me, my recently replaced charcoal canister was malfunctioning. I had replaced it with an Autozone VC120 when installing the aux tank, a year ago to avoid this exact problem. It's a common issue with the 80 series, given their age and a substantial number of guys still running them. Well, the pressure release continued and increased as the cap was about to come off. It's a good thing I had a firm grip on it or it would have been blown several feet away. Wet fuel was being blown out also. I was able to block most of that by holding the cap close to the spout. This continued for well over a minute, but what was terrifying was the sound of the fuel tanks contracting back with the pressure release! Hmmmm, time for a decision. I was not far from Orovada, just into NV so I recapped the tank, stopped the transfer and continued to Orovada and pulled into the dirt parking lot. Did some more "on the road" troubleshooting. Decided to pull the tank hose from the charcoal canister and loosely cap the tank, but Colorado was out. The tranfer now seemed to be normal. So, I topped off both tanks and headed home, but decided that on the way back, I could do some exploring. Stopped for another tank topoff and no pressure was building up, so I headed off road. Going slower with the windows down and the tires aired down I could hear what seemed like, something was rubbing occasionally. It was sort of like when I was a kid and clothspinned a card into the spokes, but muffeled. The exploring wasn't working out anyway since I stumbled on an unexpected "no tresspassing" sign and it was too late to pick an alternate rout to my destination, I decided to pack it in and headed home. A good friend,
@LandCruiserPhil, noticed my troubles when I posted on Expo what my issues were when I dropped out of the run and had a suggestion. I had not thrown away the OEM charcoal canister so was able to put an end to this problem with the fix from
his thread - Thank You, Phil!!! But the rear sag and rubbing issue still needs to be fixed. Did some research and some Air Lift air bags were ordered. They're supposed to arrive today. I've prepped the LC and am waiting - which is also why I'm posting. Here's some pics of a rig waiting for a fix:
And one of my trailer waiting patiently for action
