Welcome to the forum Alberta. What kind of RV? MH or TT. A mechanic can ck the drive train if you are talking MH. If TT I know of no true RV inspectors although there may be some in larger cities. A local experiencd rver would probably be more than glad to help. Where are you? There may be one of the forum members that are near you.
Alberta, I also see you posted your email on your profile. I would advise you to remove it as spsmmers get your email this way. If anyone here wants to pm you they can w/o your personel email add.
