jeananded, Welcome to the FMCA Forum. Please tell us what engine you have.

It might help to tell us more about your coach. Some may be willing to drive a late model but not take a chance on a cross country trip in a 25 year old coach with 9 year old tires.

If the coach meets your needs (size, layout, etc) KEEP IT. You know it well and have it "up to snuff". OR, get a newer coach and likely go through the same kind of teething issues. All three of the DP's we have owned over the last 20 years have required more maintenance to bring them "up to snuff" in the first 6 months than in quite a number of years thereafter.

https://www.cummins.com/customer-assistance Be sure to include your engine serial number.

Look forward to what Peter finds as he digs into this.

poerjrjr, Welcome to the FMCA Forum. Is it the panel that is wallowing out or what it is screwed into? If the panel itself, can you make a substitute panel from luan or other thin plywood and stain/paint to match the interior decor?

The answer is "it could" (make a difference). Heat expands/cold contracts. So cold can cause some things to leak worse. But, more pressure in both oil and coolant systems with engine running, so somethings leak worse then (not related to pressure test, but very relevant for when you are driving).

I suspect a much less "robust" Allison with a 150 HP 1990 rig. Might be an AT545.

Peter, Best advice is to e-mail both Allison with your transmission model and serial number AND Cummins with your engine serial number to verify that you both can install an exhaust brake and then from Cummins the maximum backpressure the engine was designed to accommodate. It may be that you could fit one, but the exhaust springs would limit backpressure to where it would not be effective/not worth the money.

blairarbogast, Welcome to the FMCA Forum. Since you are going with Roadmaster tow gear, I would sure recommend calling Roadmaster to inquire about a baseplate. They will be one of the first to know if the 2018 baseplate works on the 2019.

And, now???

With the Caterpillar C9, there was an ECM reflash to address this. Check with any Caterpillar dealer.

tkcoffman, Welcome to the FMCA Forum. What engine? Some have a "protect the engine" such that they will not make much power until up closer to operating temperature. I seem to recall that there was a problem with faulty sensor or ECM setting on some that would limit power past when it should be making good HP. Have you checked for diagnostic codes?

jamesbarboursr, Welcome to the FMCA Forum. If close to oil change time, go ahead and change oil and filter so acids don't build up in the crankcase. Many add STABIL or other gasoline stabilizer with the last fuel fill up. Store with fuel tank full to minimize condensation. Per Michelin and others, inflate tires to max on side wall as long as it does not exceed rim specs. Reset to correct PSI in the spring.

Smilnhere, Welcome to the FMCA Forum. Please tell us what coach you have-- most have an air dryer. If so, it has failed. Do you know specifically where it has frozen?

Yes, we need to know what brand system you have-- should be on the pad you push to activate the leveling system.

As suggested, DON'T guess. Do a pressure test and verify exactly where the leak is. Could be minor or major, but, as Steve said, it needs to be handled before you do significant engine damage.

ktw4ever, Welcome to the FMCA Forum. Enter "Jeep Wrangler" in the search box in the upper right corner of this page. LOTS of discussion.

akdarnell, Welcome to the FMCA Forum. Please tell us what chassis you have-- that will help. And, when you say it would start "using the emergency safety switch on the dash" are you referring to the boost/battery combine switch?

Call Michelin Corp directly with the product codes from your tires. Let us know what you find. Michelin 866-866-6605

Carl, I read his initial post differently. He said, "It has had 3 rooftop air conditioners (Coleman Mach 8 with heat pump / no heat strip) go bad, all because of locked up compressors... three repair shops." I read that as one A/C failed three times.

There is no "here is the best systems" choice for all motorhome/toad combinations. Tell us what motorhome you have and what you are towing. Also, how long do you intend to keep this particular coach/toad.

Lots of discussion on this as they are a VERY good idea for both coach and toad. In the upper right of this page, enter "Tire monitor" (yes, in quotes) in the search box.

Richard, May be "bending" this thread a little off course, but we found our posting in Nashville, TN to be just that-- 4 seasons but little severe weather. Ya, there was the year with a really "awesome" ice storm, but other than that .......

Richard, As we say in Texas "That just ain't rite".
