I understand your reluctance; some women resent offers from men to help with various jobs, often because they feel that their abilities and competence to handle any operation "without a man" are being questioned. I've been traveling solo for many years, and rarely need assistance with anything, but I don't take offense at all when a man offers assistance or a suggestion unless the offer is presented in a presumptive, arrogant, know-it-all manner, and/or the man continues to insist on "helping" after his offer has been politely declined with a "Thanks, but I'm good."
RVers are generally friendly people, and I believe that most of them genuinely want to be of use when they offer "guidance" to another RVer, male or female. All one can do is to offer, then move along if it's declined.
