Hi Amy, nice to meet you.
You've landed on a forum that's dedicated to all molded towables. Your Holiday Rambler is not manufactured by that method. While we may be able to give you advice, you may want to join a forum that has many more members of the same or similar brand as your trailer. They'd more than likely give you the advice you seek.
I'd suggest: iRV2 Forum | - RV Forum Community and RV News
which is owned by the same group that owns FiberglassRV. Nice people hang out at IRV2
and/or the Open Road Forums at RV.Net RV and Camping Forum ? RV, Trailer, Camper, Motorhome, Camping and Campground Information
There may very well be a forum that's dedicated just to the Holiday Rambler brand?
Best of luck!
