I’m putting this out there because I could find zero information on the 320g and hauling a smaller side by side/UTV. After measuring several times for side by side options, we went with the Honda Pioneer 700-4. The 700-4 has four seats (5’WX9.5’LX6.8’H). With our upgrades such as the garage sliding screen and glass doors and deck railings, we lost 6” of garage length from 11’ as GD claims. The Honda Pioneer 700-4 fits with approximately 4”-5” front and rear. Clearance reference the happy jack and door frame was plenty. For extra head room, I folded down our dinette seats/bed flush with the wall. Securing the side by side down with ratchet straps was easy. There are plenty of tie down points. We used 2” tie down straps with ratchets at 6 frame points on the side by side to secure it. It didn’t move an inch on a 400 mile trip. No issues at 65mph.
