I have an 89 allegro 27' on a p30 chasis. it is stock, haven't done anything to suspension yet. This thing goes down the road like a boat and rolls and leans as you go. I need to tighten it up. I plan to put on bilsteins but what else should I do to tighten up. Has original tires which I will replace-any thoughts on a type that might help this problem?

Rick,
The shocks are selected for the chassis, not the coach upfit. Just go to Ford Truck, work your way to Class C, you'll see E350, then 555033 and '34 for front and rear. Based on what I've read, I think I'll put Bilsteins on mine. '83 E350, same shocks as yours since they go '75-'91. Question, do you have steering wander and have you tried any kind of steering stabilizer?
God Bless, jd

Jd,
Thank you for your input. I see the light.
Our MH has minor steering wander. 36k mileage. I will address that in the future (probably next year)because we have our money budgeted for different things right now and it is time to go camping.
Take it easy

Mike,read this thread over again and found your
reply of Feb 9th.I know I missed it before so can you explain what you meant about over inflation re the wheels as the tires we have R8/19.5 are ment to be inflated 100-110psi according to the sidewall they are also all steel belts.Can you tell me how to find out if they are in danger.

Jim: Since no one has posted an answer to your question for the past three days, let me try.

Someplace on your rim, generally on the flat area should be posted or stamped a number that would indicate the maximum amount of tire pressure that the rim can SAFELY handle with out splitting apart. In the case of my P-30 Chevy rims, the number 90 is stamped into the flat area of the rim. I also run 12 ply tires that has 125 lbs stamped on sidewall but no way would I consider running that much air in my tires. Because I kind of picky about weight, I generally cold pressure my tires from 75 to 80 lbs. Might consider 85 but that would be max for me.

What I find interesting is the number of “expert” tire people that is not aware of this restrictions. It almost happen to me and just this past weekend, a close friend who put new tires on his rig was over pressured by his tire supplier. Probably the easiest way for you to check would be to go to a rear dual, pull the hub cap if you have one, then carefully check around the flat of the rim for any number stamped into the rim. It might be hard to see due to dirt or being painted over but it should be there.

Hope this answer your question.

Thanks Marty
Thought all had lost interest,will check that out it is far better to be safe than to suffer the consequence of rim and tire blowing.Had a 1200/24 blow apart when I was a kid when mounting outside dual sliped went down lock ring popped tire and I (210 lbs)straight up 10 to 12ft as told by bystanders as I was out cold The Doc that looked at me said the only thing that saved me was I was built like a brick ----house so you can understand my concern I hope.
Thanks to all for all past help I have recieved in the past and looking to all yor help in the future.

87 Bounder on Chevy chassis - Tires started blowing out at 10,000 miles so I replaced them with radials - helped the roll and wander.

94 Southwind on Ford - Tires started blowing out at about 18,000 miles. Replace with 10 ply radials, helped the roll a bit, enjoyed not having to worry about blow-outs.

01 Allegro Bus - No roll or wander - guess its the extra weight of the rig and the fact that it is not loaded to max GVW.

I'm sure the other two rigs were loaded to max on the factory tires and the tire failure was due to the heavy loads. They were properly inflated and had about 3/4 of the original tread remaining?? Not much load capacity on the earlier gas rigs, by the time you subtract the dry weight of the vehicle from the rated GVW then fill the fuel and water tanks and throw in some gear its easy to be overloaded.

The newer rigs have higher GVW ratings but it still wouldn't be a bad idea to load it up then find a scale. Best is to get a weight on each corner then compare the weights with the ratings located on the tire side-wall.

The grand old thread that just won't die! Hopefully today I'll finish up a front end refurb project on the '83 E350. Changed the bushings where the twin I-Beams pivot at the frame last week. Raised front end on the leveling jacks, put jackstands under frame, removed wheels, lower shock bolts and upper sway bar nuts. Axle swings free, held up by the spring since spring is anchored to axle at bottom and frame at top. Pressed bushings out and in with AutoZone loaner balljoint press augmented with some sockets and large washers from my own stuff.
Over the weekend, replaced the radius arm bushings. Hard to find the correct brand, the Perfect Circle number stocked in several places wasn't right. Found the best fit and deal at NAPA. They're neoprene, will take a lot of torquing to compress into place. Decided the radius arm bushings were the cause of the toe-out I adjusted a year or so ago. Expect I'll have to reset that, will report what happens.
Hopefully today I'll get the second front shock changed. Going with NonBilstein. Local availabilty and price on a generic for Monroe Gas Magnum RV.
Well, back to it. Will let y'all know how all this works out.
God Bless, jd

I have a 92 Winnie Brave 31' on a Ford 53 chassi, I bought it 2 years ago with 15,000 mi. I first installed the Bilstiens which helped some of the rolling. Last year I put 9000 miles on it and was OK with it's handeling. This year I drove it to Alaska and I the driver got motion sick form time to time. When I got home I installed the Davis true track bar and while I was under there I noticed the rubber mounts (like the rubber in a shock mount had broke up and was gone. I installed new rubber bushings for the front sway bar and between the both it is one heck of alot better to drive. I wonder how much better it would have been had the rubber mounts had been good before I added the Davis true track bar. I did talk to someone on the way up who added the Safety steer kit to his 04 Winnie and said it made all the difference in the world in wind and passing trucks. That may be my next purchace. But no matter what you do they arn't going to drive like the car you drive every day. They are a big box usually on undersized chassis. I too have followed diesel pushers in the wind and could see they had their hands full too.
