Experts away!
An RV forum I belong to has two "experts", who indeed are well versed in the motorhome field.
Problem is they are jerks. If you have the temerity to disagree with them, or give advice, they go all sarcastic and venomous on you, and heaven help the fool who proves them wrong. The best one just alters his stance over several posts until he agrees with you. The other one considers it his mission to take you down. Anyhow, since they do have good advice usually, the best way to handle it is like the "Soup Nazi" episode of the Seinfeld show. I just read their posts, and avoid all other contact.
