Older Class C with 350 Chevy Engine?

Hi folks, I have found an older (1979) C class Midas 23 ft motorhome that I can get for a reasonable price that has a 350 Chevy engine in it.
If there are any of you that have experience with this rig I would like to hear you input on it. It has around 60k miles on it.
Anything in particular to watch out for?
Thanks in advance.
  • Thanks Fred, good to know about the tire and rim interchangeability. Also my friend looked the roof over pretty good from the inside, and reported no visible damage from leaks.
    About the EPDM two part roof coating, do you mix the two parts before application? Or is it applied in two parts?
    Thanks for your replies.
  • The rims should be easy to replace with 16" rims from a more recent van. Not a new one, but anything from the mid 80's should be fine.

    400" engine is the same as the 350, with a little more power. Three speed auto, and it will rev up pretty high at 65 MPH, might not get 10 MPG at 65, but should at 55.

    I had one, and put in a digital transmission gauge in it, and it read kinda high temps. I installed a larger transmission cooler, and it was fine after that. Check the fluid. If it is red, then the prior owner probably changed it already, and it should be good for about 10,000 miles. If dark red, then change it soon!.

    Check the roof. If it needs repair, or replacement, consider a two part EPDM roof coating. Don't trust single part roof coating, as they can dissolve when under water for a long time (mine did).

    Fred.

    IMO you should be more concerned with the condition of the house portion. While the engine, transmission and chassis condition are important, in that vintage parts should be readily available and not too expensive. On the other hand, leakage and rot in the house portion can quickly add up to a basket-case money pit.

    Thanks for that advice.
    My friend that is checking it out says he's going to check the plumbing by pressurizing it with a hose, but it does need a house water pump.
    Also, there seems to be an issue with the heater. The fridge, oven, and range top all work.
    The engine is actually a 400 inch small block and not a 350, which may, or may not be a good thing. It has 4:10 gears, which sound about right.
    It needs two front tires, and they are 800 16.5's. There is something about that size tire that I think is not good, but I can't remember why.
    The guy says he gets about 10 mpg with it. That sounds about right?
    I told my friend to hold off for the moment, and he is going to try to price every thing out before I shoot him an offer.

    With that low mileage my first question would be how long it has sat in one place?

    IMHO run don't walk away from any MH that has been sitting sinking into the ground. WAY too many problems and not worth any low price. JMHO.

    Thanks for the advice. To elaborate on the sitting, I talked to the guy over the phone and he uses it every weekend when they have an event as he and his son race motocross.
    I'm betting he has already addressed most issues.
    I'm just hoping that if there is anything in particular I should be aware of, maybe someone will chime in.
    Anyway, I have a friend going out to inspect it for me before I buy to ensure it is mechanically sound.


    Good, sounds like it might be a great deal for you. Most of us who do sporting events regularly every weekend with our MH's do tend to pay attention to details and take care of all maintenance issues regularly. because of how often we use them. I wouldn't think twice about buying a MH with offer 100,000 miles on it from a fellow sporting event camper! :B

    Good Luck! Hope it turns out to be just the right new to you MH.

  • How long has it been sitting and how handy are you at basic maintenance and hand tools? Tell us about the unit. The 350 engine is a plus.
