## Questions & Answers

**Q: I have a  2021 3791rd montana  anyone know what Size  I should  purchase  does anyone know what model number?**
A: AD34857  should fit .  My 5th wheel is 40ft. Cover fits fine.  Cover all sharp spots with swim noodles, and you should be fine.

**Q: What guage is the best to buy for Michigan weather winter.**
A: I don't recall that there is a guage option with the ADCO cover, at least there wasn't when I bought ours.  We used ours on our 40' 5th wheel last winter here in north Idaho. We had several feet (3-4) of snow and the cover work perfectly. I think some folks who have had problems either put it on too tight, or not tight enough. I adjusted ours to allow a little movement; but, not tight enough to stress any of the seams. I would recommend it .

**Q: We recently purchased a 36 ft 9 in fifth wheel, would the cover need to be the 34-37' or the 37-40'?**
A: My RV is 42 ft I purchased one that fit a 40 to 44 it fits perfect and its nice to have the extra size for wiggle room. They are a little tough to get on but not too bad. Hope this helps.

**Q: does this cover come with a storage bag/sack or container for storage when not used?**
A: A sack bag... but has never been able to get it back in it.... I store it in a 50 trash can with lid.... works great
