The above is probably very typical of the vast majority of RVers. Lets face it.....we all like to brag a bit about our accumulated knowledge in the fine are of RV 101. But its only good sense to wait to be asked....volunteering information can usually be met with someone digging in their heels and sometimes a not so pleasant "go to hell, I know what I'm doing". Especially if there is a wife present bending the other ear with I told you so's....
Seems like the more stupid the activity, the more we have to keep our mouths shut :) Gotta be somekind of rule about that.
