weight limit on beds

[Jdog2019]

It's not 150lbs. That's less than one full sized adult. It's usually about 1000lbs based on manufacturer. I couldn't find anything in the owners manual and brochure for your trailer. The next step is to contact them, which you apparently already did. So you have a real stumper there.

Thanks. We found the label on the bed and it says 1100 pounds.

There are stickers at each of the bunks on my 07 coachmen clipper 086 that read; 1200lbs max. on front bunk and 1000lbs max. on rear bunk however I don't think I would even come close to testing that. You should contact the manufacturer of your make and model or a dealer.

I have a 2003 Viking model 1906 with the same markings on the bunks. 1000 on one and 1200 on the other. Even though I know that it still scares me to move way out to the end of the bunk at night. I'm only 250 lbs, but I still stay pretty much to the inside. Just a big scaredy-cat I guess!
