My friend, Laura, told me today that she thinks she has two able-bodied neighbors to help her out. If no resolution, she'll get back in touch. THANK YOU, all, once again for the great & speedy advice.
(What started out with me asking for a reliable website to help out Laura turned into a bit more, & gratefully so! But, at this point, maybe this is more appropriate for Owners Helping Owners? Or not, since she's deprived & her trailer isn't fiberglass?
Also, I think an Admin person needs to take care of this? And, lastly: surely I can find a few more spots to place question marks??)
