New Crusader Electronic Leveling Questions

We just picked up our new 290RLT TE a few weeks ago. We have been putting it through the tests and so far we love it!


My main question so far is with the electronic auto leveling system. Stability overall has been a question mark for me even with a king pin stabilizer.

First of all, I read on another post that the landing gear are designed to have a slight outward pitch for increased stability. All four of my landing gear appear to have a very slight inward pitch. Is there a chance that my gear where installed on the wrong sides and if so, is there a way for me to check/verify if this is the case?

Second. When following the "Auto Level" procedure on two occasions, the procedure completed successfully but it raised all four wheels completely off the ground. At first I was not sure if this was normal but I read in the manual that the wheels should not be off the ground. I put blocks under the wheels and manually lowered the rear then front until the wheels where on the ground and the front to back was level. Just not sure why the "Auto Level" would complete in a condition the manual says is unsafe.

Any help would be appreciated. Thanks.

I was the one who indicated the slightly outward pitch is normal on landing gear. I was referring to our standard application not realizing you had the Ground Control system - sorry for the confusion.

We can have a technician contact you to offer some hands-on assistance for your questions. PM me your name and contact info if you'd like.

the same thing happened to me (all 4 wheels off gnd) until I stopped it. Please let me know what you find out about this.

I had the same situation this past week where all 4 wheels came off the ground. I made adjustments manually, lowering the jacks until all wheels were on the ground again. The rig was slightly out of level but much more stable. We hardly noticed the out of level.
I would be interested in the response as well.

I will keep a close eye on this thread as our new unit has auto leveling.

Our 360 has auto leveling and have no issues. Hopefully they get this resolved for you.

I'd try page 25, zero setting the control

We are researching this situation a little more trying to get good answers for you. Lifting the tires off the ground is not something we've come across before but obviously it's happening. We know about the Zero Setting Recalibration process but are inclined to think maybe something else is at work here. Be patient - we are on it.

Thank you for the quick attention and the clarification about the landing gear pitch. More of a curiosity than a major issue at this point. Both times it was on less than perfectly level dirt/gravel site and it was pretty easy to correct. The only real issue is that the return to drop off feature doesn't work after I have to manually tweak it. I can try the zero level procedure but I am not sure if that will fix it as the trailer is perfectly level when it completes with the wheels off the ground.

Don't do the zero reset. Give Rv guy some time. He'll get it solved.

There's only one situation that we are aware of that can cause the unit to be lifted off of the tires:
If the unit is NOSE DOWN excessively with the REAR JACKS EXTENDED to the ground when you start AUTO LEVEL, the system will be forced to raise the front end up to level. This could lift the entire coach off the ground.
After playing with the system today and talking with Lippert, this is the only scenario where we could make the tires come off the ground. The unit needs to be "relatively level" before you drop the rear jacks and engage the AUTO LEVEL. This might require you to manually adjust the front legs some before starting the process (which is covered in the Operation Instructions).

It is entirely possible that the programming needs to be reset to ZERO CALIBRATION, but that sounds unlikely in most instances. However, that process is spelled out in simple step-by-step instructions in the Owner's Manual. Before doing that, we would recommend some technical assistance either thru a dealer or over the phone with a Lippert Technician.

Since we are unable to replicate the issue in any way except for what we described above, we believe this will help in most instances. However, we stand by waiting to provide additional assistance if our feedback doesn't solve the problem.

I was definitely not excessively nose down when I encountered the situation. In fact, after it first happened when I dropped it off, I manually lowered it to get the wheels on the ground. I verified (electronically and with a level) that we were level. I restarted the system and I hit the Auto Level again out of curiosity. It again raised it off the wheels even starting from a level on wheels position. We are having some weather here now, but I will attempt to replicate and capture some video in a few days. Thanks for the info.

I too, started with a level unit when mine lifted off the ground.

The second time I tried it I put pieces of 6x6 under the frt jacks so they didn't have to extend so much AND to help with the unstable boat feeling inside....leveled fine this time.

My driveway is on a slight incline. RV Guy's fix solved my similar auto leveling dilemma. Greatly appreciated...

It sounds like in the two cases that started with pretty much level, what the auto-leveler did was to extend all of the jacks to max-extension. There may be a clue in there somewhere. It might be worth it to see if any of the legs can be manually extended *further* than the leveling system leaves them.

My unit did this today, and I have pictures of it as well. The unit was relatively level before we attempted auto level. It was the end of our first trip and we were too tired to deal with it further so I just used manual mode to get it close.

I will return to the storage unit and attempt to determine what I must to do avoid it the next time.

At this point, we have not been able to recreate this scenario with a retail customer. There are a couple of posters who have experienced this. If you would like to PM me, give me the last 6 of your VIN and a contact number, and offer to help us figure this out, it would be greatly appreciated.

RV Guy I will send you my info and will definitely be willing to work with you to figure this out. I can re-produce the situation at my storage yard whenever I need to.

In order to sort it out I put one course of lynx levelers under both sets of tires and then re-leveled and the unit did auto level without issue.

Further to this, on a trip this weekend I was on a slightly sloped site left to right. Not overly bad, but sloped for sure. The auto level process this time lifted my right side tires off the ground. Once again I put one course of lynx levelers under my tires and re-leveled and it was OK.

Shouldn't the system perhaps give a warning before attempting to auto level that tires might be lifted? Not sure, but it's hard to tell what the system will do before attempting to auto level.

Will damage eventually occur if the unit consistently lifts tires off the ground, if even only for a few minutes?

Hi RV Guy. Sorry I haven't responded, but we are getting one wave of snow after another here in the Denver area. Haven't had a chance to play with the gear. Also, thanks for checking up on this and for having your tech contact me. I hope to get this resolved shortly before we head our for some fun and better weather!

We have not had a problem with the auto leveling. I have noted a mist coating of oil on the cylinders. I also have to re-level every 2 days. Is this normal?
