Is CG info available from MFG's

I notice most of the TC's I have looked at on the internet post CG(center of gravity) information. I have not been able to locate this info for Class C's on the Mfg web sites. Nor have I seen any info on UVW weight, or weight on front axles or rear axles. Is there a way to find this info before you buy? Or at least a method to estimate the weight distribution? From what I read it is more important on shorter Class C's.

    Actually it’s more of an aid to make sure the COG is ahead of the axle.


    Yes, my tc’s had COG markers from the mfg. I also remember how crosswinds affected handling on my basement model tc. It was more difficult to operate than my non basement tc , on the same truck.
    I remember crossing some bridges where i thought of wearing a life jacket. :B

    I am a retired engineer and I know of no way to know that ahead of time if the manufacturer doesn’t provide it. After I bought my motorhome I loaded it up as good as I could and then had it weighed each axle separately.From that you can determine the CG at least from front to rear. I know of no easy way to measure the height of the CG or even how important that might be.To play it safe I never take the corners so fast that it becomes unsafe.
