What I learned about big DP's at the FMCA rally.

1: You better like bath and a half MHs as I could not find any that were not, although I did not look at every 40' or bigger MH at the rally.
2: Dark interiors are the norm with some so dark they look black at first... actually a dark brown. Out of a dozen I looked at only one was what I would call light and airy... pale white tile floor through out, light brown counters, and cherry cabinets, but white upholstery.
3: O M Goodness, they are heavy. A 40' Tiffin with a 24K rear axle (legal for 4-5 years now) and six 315/80/22.5 tires requiring 130 psi in the two fronts and 120 in the four rear tires.
A 40' Jayco with 315s/130psi on the front and 295s/115 psi on the rear.
A 45' Tiffin with 315s all around and requiring 130 psi in all eight tires... a 17K front axle and 23K drive.
There was a 40' Newmar with only 275/70/22.5 that needed 130 psi in the fronts and 120 in the four rear tires.
Spartan had their bare chassis with 365's on the front and tag and 315's on the drive, but n sticker on psi... yet to be determined.

I guess I'm old school and do not like to run MAX pressure in my tires.

  • Although our rig has light oak woodwork, I feel the darker woods look richer. However, they do make the interior dark, which makes it appear smaller IMO. We are not a fan of the bath and a half layout either, but then again we only travel with the fur kids. Our biggest complaint is the extensive use of leather furniture. I don't like leather in cars or at home and luckily for us we found a rig with a cloth covered couch. I can tolerate the leather on the driver's and passenger's seats, but not my first choice.

    Most mfgs don't even offer a light color.


    We've noticed it for years that the dumb-a$$ manufactures seem to think all humanoids love DARK interiors. Well, we searched and searched and came up with what we have now, and have had for almost 6 years. Our coach is an '04 Itasca Horizon, 36GD with the C-7 330HP CAT. It's interior is called "Washed Maple" in the brochure. It's bright and nice. The upholstery is also lighter with brighter colors in it. All the fixtures and hardware are what's called "Brushed Nickle".
    The old "Oak and Brass" was dated waaaaay too long ago for us. So, we were really happy to find what we were looking for.

    As "bath and a half", well, not exactly sure what you mean there. Ours, like many has the shower on one side of the coach and the latrine and sink, on the other. I don't think I would classify that as a bath and a half. Now, if you're speaking of a full bathroom in part of the coach and, another bathroom or, at least a latrine or sink, in another part, yeah, I guess that's a "bath and a half".

    Tire pressure? Well, that's determined by the load, not necessarily the statement on the tires or, drivers I.D. plate. Get a coach weighed, AFTER it's loaded for a trip, and take that weight to the tire charts of the manufacturer of the tires on the coach and see just what THEY say about the specific tire pressure for the type and size of tires vs the weight they will be carrying. Good luck.

  • As others have said you would only run max pressure if you were at max load. As for the bath and a half and the dark interiors the manufacturers are building what sells. If you really want a light interior I suspect that if you order it yourself you can get light interiors from the factory rather than relying on what the dealer ordered and put on his lot.
  • You shouldn't have to run the tires at max pressure. Inflate them based on the actual weight they are carrying, not the max pressure listed on the side wall. I have two 315s and six 295s, none are anywhere near max pressure...on a 49k coach.
  • Coaches are getting heavier. We are at 55,500 lbs, we don't run any of our tires at max pressure. We have 365's on the front and 365's on the tag, 315's on the drive axle. I'm running 115 on the fronts and about a 100 in all the rears.

    We have a built-in tire pressure monitoring system showing that we are about 5 lbs. over for on all the tires for a cushion.

    365's are amazingly wide tires.

    We like the medium dark interiors. When we built our coach, we wanted a 'library' comfortable feel. We have walnut and zebra-wood cabinets with walnut flooring (medium dark brown). Our leathers are a medium toffee color. I certainly didn't want cream or white leather.

    Safe travels,

  • Even Newmar Dutchstars have size 365 tires! Bigger than Tiffin Zephyr and American Coach Eagle tires.
