air bags can sit for years also.
i for one after dropping $60-$80-$100 + grand usd on a rv. sure hard to get up the cash. but if i could i would go air bags and disk brakes.
sure mostly nobody in the trailer. but what about everything else? even the walls would do better riding on air.
and disk brakes. do i have to spell out that one?
having a air compressor is no problem. a little one on the rv with a tank. and a duplicates set up on the tv. or a better compressor on the tv, with a larger tank, and air connection to the rv. and there is this little valve used on trucks to level out the truck, trailer, so no need to "adjust as needed.
maybe even air brakes for a light-duty truck? is it possible?
good to have more ponies for the get up and go. but far better to stop even faster.
