About this RV

Keystone Avalanche fifth wheel 378BH highlights: • Full and Half Bath • Bunkhouse Suite • Loft • Dual Entry • Outdoor Kitchen • Kitchen Island You won't believe how many extravagant details have been included in this Avalanche fifth wheel! Traveling with guests or extended family will be easy to do with the separate bunkhouse suite and master suite. Since the master suite has its own master closet and entrance into the full bathroom, and the bunkhouse contains its very own half bathroom, everyone will have their own private space to get ready each morning. On top of that, you will also be able to choose where you want to prepare and cook each day's meals with both a spacious indoor kitchen with full amenities, plus an outdoor kitchen. There is even an outdoor entertainment center with TV. You can also add an option or two such as a washer/dryer and/or a residential refrigerator. And there is so much more to love about this fifth wheel!

Questions about this 2023 Keystone Avalanche 378BH

Is it still for sale?

Fun Town RV’s website listed it for sale on November 5, 2026. RV Shift checks dealers’ websites about once a day, so ask the dealer to be sure.

What does it take to tow it?

RV Finder’s estimate: it needs a vehicle rated to tow about 15,200 lb, with a fifth-wheel hitch. That is its 13,908 lb dry weight plus 1,200 lb for water and gear, rounded up to the next 100 lb. RV Finder shows whether it is within your vehicle’s published rating, from the maker’s own towing guide, and checks tongue weight and payload too. Confirm your numbers in your owner’s manual and on the sticker in the driver’s door jamb. Check it in RV Finder
