Expert Answers about Keystone Alpine Fifth Wheel


  • Replacement Hatch Door for 2022 Keystone Alpine 3620RL
  • Hey Harold, welcome back! The B&B RV Electric Hatch # BM32MR is the closest match we have for those dimensions. The cutout is 6" tall x 11-1/16" wide with outside dimensions of 7-3/4" tall x 12-5/8" wide. You will have to expand the existing cutout slightly for this to fit. If you really want to avoid that, I would check with a local RV repair shop to see if they have an exact match. Where are you headed next with the Alpine once you replace that door?

  • Replacement Leaf Spring for a Keystone Alpine 3700FL
  • Hey Bruce, thanks for reaching out! The only leaf spring we have that matches the 7,000 lbs rating of your axles is the 24-7/8" Long 6-Leaf Double-Eye Spring # e64SR, but you'll need to take the load off of your current leaf springs and measure center eye to center eye to see if that length matches what you have. If it doesn't match, please let me know what you found your leaf spring length to be and I can see if we have an alternative solution for you!

  • Looking for Wet Bolt for 2021 Alpine 3220 RL
  • Hey Joshua, the part # 126B2 that you referenced should be the correct wet bolt. Take a look at the dimension picture I attached to this page and let me know if what you have would work with this. If not, let me know what would need to be different and I'll see if we have it.
