There's lot of knowledge here and most are quite willing to try to help. So what's the plan for the old Brave? Lots of fixing and rebuild or just thinking that there are going to be things to learn?
One way to cut through lots of confusion and time wasted will be to post as much info like year, make and model of RV as you ask the first question. One reason I hate doing any business by text is the person rarely tells enough to know what is needed, so rather than make one simple phone call and get a response, they are so busy it may take six texts and four hours to get the right info!!!
Hope to hear what's up with the project!
