I have had this motorhome for 8 years and have never weighed it. I just kept a certain pressure in the tires. I know this goes against the grain to some on here. I just want to see how many of you ...
I check my coach weight yearly when we hit the road or our yearly vacation. Find I'm pretty regularly 2000 lbs. under GVWR of 18K lbs. loaded for two. Also I have more capacity in the tires aired up to minimum, per the OEM tables, then I do in my axles. For our weekend travels I loaded much lighter so I don't worry about it. Also I have a TPMS to watch the pressure.
If I was a full timer I would do the same a Dennis, every couple of fill ups.
