  1. Weather is crap right now and the coach is in storage...sadly, outside. I think The jacks are Atwoods but it will take a day or so to get to it to look at the manuals- New coach to me, just celebrating a 2 week birthday. It will get north of 20 degrees next week and I'll run the jack down and clean them off.... will send updates as things develop.

  2. I  was told electric jacks didn't like the cold. Sure enough it was about 20 degrees today and it took about 4 false starts before they went up.

    Press the button, they would go up about a second and stop. Reset and then same thing.

    After 4 tries the jacks went up, except the passenger side which only went up about 4 inches. I cycled them all down and then they all went up without a problem.

    So..... Do I have a problem or is this somewhat normal?

  3. My desire for TPSM coming from a trip I made when, in the rain, I noticed bits of the rear tire on my 5th wheel flopping in the rain. I hadn't felt or heard a thing and had no idea how many miles I had gone prior to seeing the flopping tire. Something I would not have seen if it were on the right side as my mirror couldn't be trained to see the back tires properly. I've heard similar stores of the inside rear on duel's. So... an alarm for tires I can't see on my new motor coach gives me piece of mind.  Thanks to all proving great advice.... this is a good community. 


  4. I understand I should check tire pressure every day, first thing. However, if the overnight ambient temperature is 25, but I know I will drive into 65 within , say, 3 hours...... will this likely  increase my tire pressure more than the 20% increase the factory recommends for a high pressure alarm on my TPSM system I will be adding?

    What size Fifth Wheel are you currently pulling?

    I ve got a 38 foot weighing about 12,000 pounds. Truck and 5th wheel combined weight 20,000 I can do 70 all day and get about 10.5 mpg. I've got 800 pounds of torque now so when I think of a Dp that will weight say 40K.....almost everything seems under powered.... perhaps I need to learn to enjoy the ride.... I'm newly retired and still haven't gotten use to the idea... " I don't care how long it takes to get anywhere."

  6. 37-38 foot in length. An engine developing  at least 1050 pounds torque(more it now seems). able to tow 10,000 pounds. Less than 180,000$...   I really like the Dutch Star. Tiffin bus or to a lesser degree Tiffin Phaeton. I'm from Illinois but could find myself easily in the Texas to Florida area if something interesting comes along.

    No, the speed delta on a grade will not be 35 vs 50.

    Here is an excellent discussion of coach performance written by Caterpillar Corp.  Physics is the same for Cummins, or any other engine for that matter.  Go to the page showing HP demand at rear wheels on 6% grade: http://forum.dieselrvclub.org/index.php/topic,6594.0.html

    BTW, there is a lot of other helpful information on the Diesel RV Club Technical Site: http://forum.dieselrvclub.org/index.php?action=forum


    Agree with Frank, another variable is the EPA specs that the engine meets.  As happened with gasoline engines in 1975 when catalytic converters were introduced, HP and MPG both went up.  Same for diesels, with most improvement in engines built after 1/1/2007.  But, they newer ones are more complex and require DEF.


  8. I've been looking at a Dutch Star 3623 that has an ISC360HP engine. I'd rather have the larger 400 but that configuration seems difficult to come by. The issue of more torque  is relative to a decision. But, I might be persuaded if the fuel economy was markedly better. The simple question is; Given the same or similar configuration......what is the Fuel economy someone has gotten with  the 360 and what has someone else gotten with a 400?  Chime in with your engine and weight specs to make analysis easier.  To help with the torque question.... what speed you are going at the top of some famous mountain pass. I don't expect to do as well as my 2010F250 400HP/800lb torqe pulling my 5th wheel.... but I'd like t know what to       And yes, I know that If I have to ask about Fuel economy I shouldn't  buy. But the engine configuration is going to stay with me forever.. but I am asking anyway.
