I've tested that already 4 with no attachments fit but I have to get more straps. I'm going to.take the side ramp off an make it removable an add in some angle to look like a trailer side before the show
Yup pop traded up to the 18ft on so he could get them on easier and then the attachments can stay on.
I have that issue with mine with the attachments also could easily get another in with nothing mounted. Would like a bigger one but cannot justify and $$$ is not there right now.
