We are anxiously awaiting our first GDRV, rolling off the line on March 15. Trying to get everything lined up. I would like to add slide out toppers (awnings) to my 337. I have heard that Carefree is the brand GD recommends. What are some of your opinions? I also hear that there might be issues working around the dinette slide patio awning, at least with other brands other than Carefree. Then lastly, has anyone installed these themselves?....thanks in advance, I’m sure I will be posting more questions later...
