Our RTV, when new, the bed had a " zzzzzzzzzzzzzzzzz " buzzing sound. Which was caused
by the bed viberating. The sound only came when you was just about to come to a stop.
OR, when you where just taking off, it would buzz for about three to five seconds. It like to
have drove me crazy. Then, the light bulb went off, I installed four Limbsavers, the little
round objects that we use on bows & crossbows to tone down the sound of the limbs when shot in the woods. It is more of a damper thingy. Anyway, installed them, and " puff " , the
sound no longer shows up, ever !!!!
