Let me start off by saying I'm new to this forum and new to owning a toy hauler. I recently purchased a XLR 27HFS and I love it!! with that being said I do have one question. Can I load my 2 atv's (1000 lbs) in my toy hauler withouth it being hitched up to my truck?
Personally I wouldn't.
While you may be able to get away with it if "you're careful", I would guess that whatever stabilizing jacks you have and your tongue jack won't tolerate it for long.
It wouldn't be for storeing but for loading the camper the night before and having to use my truck the next day for work or store runs before we hit the road. How about possibly hitching up, loading the atv's, drop stabilizers and tounge jack, and unhitching?
