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".

LVH2468, Welcome to the FMCA Forum. Much of that depends on what part of the country you are in as well as what kind of coach you have. Here is one of the largest in the country: https://www.pplmotorhomes.com/used-rvs-for-sale/diesel-motorhomes?sortBy=price+asc& Currently showing 130 DP's for sale, most on consignment.

Totally agree.

Very easy to verify: Even overnight, battery voltage in the absence of a charger will dissipate the surface charge and drop below 13 VDC-- even headlights for 5 minutes is enough to accomplish this. With a converter or charger on, battery voltage will be around14 VDC, particularly right after turning off shore power breaker and back on (so the smart charger goes into bulk mode). So, do this and then measure voltage at each battery bank. If chassis battery is the same as house, the chassis battery IS being charged. If chassis battery voltage is lower, it is NOT.

Consider using a terminal strip. Crimp on "eye"/ring connectors and screw then to the terminal strip.

Another option: Sounds like it could be more related to your leveling (IF your leveling system starts by dumping air in the air suspension) than the air system PSI or ride height valves/bags. Just wondering if the leveling system is going into "leveling mode" vs "travel mode".

rgains41, Welcome to the FMCA Forum. While both ride and handling are somewhat subjective (same as on cars), many consider the 8 outboard suspension coaches (some Monaco products and Foretravel to be close to the top. Alpine is also near the top-- like the above they invested extra $$ in the suspension. There are some recent computer-controlled handling features that many really like (but I have no personal experience, so will not comment).

Likely several factors, like state income tax??? But, if only thinking about annual registration, in Texas, for the last couple of years, cost is very dependent on WEIGHT of coach. With more details, we can be of more assistance.

Ernie, You are a true craftsman! WOW

Have you checked RIDE HEIGHT?

Carl, I agree-- "to a point". If the FMCA IT department senses an attack and institutes protective measures, I am not sure it is reasonable to expect forewarning. Agree, if it is to be in place for more than a short time, it would be helpful/thoughtful for them to make a post to that effect.

I e-mailed my contact on the FMCA Staff yesterday and got this reply: This is totally normal, as it is just extra security for all of our domains. There was a bot that was attacking our site and was trying to compromise it, which in turn made our site slower. We implemented additional security to resolve the issue which will help keep attackers from reaching our sites. It has since been turned back off.

My information shows that starting in 2003, the P chassis used the GM 4L85E.

Sorry, Portland, of Portland cement is in England (been there, done that). But good try. Hopefully, Sillysailor will let us know which Portland is their destination. We are here to help, but need a little better defined geography.

That damage is generally caused by a loose connection. Loose connection= resistance=heat= burned wire.

Really depends on power to weight, design specs of cooling system, condition of cooling system, etc. Overheating on a DP is not that uncommon, particularly in 100 degree F temperatures on long grades. Knowing how to identify when your coach is likely to overheat and "driving around it" is something that all DP owners should have thought out ahead of time. "Plan B" is part of the heavy vehicle experience. Yes, we have climbed the Tehacahapi/Bakersfield grade in July early afternoon (driving from Flagstaff). No overheating in rear radiator DP. Just selected a gear/speed/throttle that worked and "toddled up the hill". Others passed us, but over half were on the side of the road before the crest.

wood6406, Welcome to the FMCA Forum. Not a HP issue. No, you won't be the first to the top of hill, but you should be able to drive it such that it does not/rarely overheats to the point of alarm. Choose a gear and throttle such that you still have a little throttle left (flooring it will still increase speed). You are in the correct RPM range. Assume this is a side radiator/CAC. If so, you also need to check that the fan is cycling to HIGH as temperature rises above thermostatically controlled temp. 160-170 sounds on the cold side for a 2001 ISC. About the only other maintenance I would do is replace the thermostat with a Cummins speced for your engine serial number. A thermostat can hang up/only partially open.
