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?

  • Will Gen-Y Hitch Shock Absorbing 5th Wheel Pin Box Work With Andersen 5th Wheel Hitch
  • Hey Gary! The Gen-Y Hitch Shock Absorbing 5th Wheel Pin Box # GY68GR will work with your Andersen hitch. However, I can't say for sure if you will still be able to jackknife your trailer. The Gen-Y Hitch Executive is roughly 2" shorter than the Lippert 1621 or 1621 HD pin box which means the clearance between your trailer and tow vehicle might be reduced. What kind of 5th wheel do you have?

  • Recommended Stabilizing Kit for Lippert Auto Leveling System on 2017 Keystone Sprinter 5th Wheel
  • The auto leveling system on your 2017 Keystone Sprinter is a Lippert auto leveling system, so the stabilizers that I recommend are the JT's Strong Arm Jack Stabilizer Kit which are also by Lippert and confirmed to work. If you have more than 58 inches between your front landing gear legs, then you will want part # LC191023. If you have less than 58 inches, then you will want part # LC191024. You will also need the Adapter Lug, # LC314592, for the rear leveling legs.

  • Is It Okay The Lid On MaxxAir 4400 Does Not Fully Open With Vent Cover Installed?
  • Your MaxxAir 4400 on your 2021 Alpine 3910RK is still going to operate correctly even without the lid fully opening with the MaxxAir FanMate RV and Trailer Roof Vent Cover # MA00-955002. The lid on your fan only needs to open 50% to allow for the full circulation rating on your fan. You did select the correct vent cover for your fan.

  • Is Prodigy Brake Controller Compatible with Electric Over Hydraulic Actuators
  • Hey Conyers, if its the original Prodigy brake controller it is not compatible with electric over hydraulic brakes but if it's the P2 # 90885 it is. The easy way to tell the difference is to look at the color of the numbers on the display of the controller. If they are red it's an original Prodigy. If blue it is the P2. If you have to upgrade to the P2 it's super simple as it plugs into same harness and uses same mounting harness.

  • What Replacement Hydraulic Jack Assembly do I Need for My Generation 1 14K Right Side Leg?
  • Hello Sal, Since you have the 1st Generation silver with 6 holes, you are going to want the Replacement Hydraulic Jack Assembly for Lippert Level Up 5th Wheel RV Leveling System - 14K - Gen 1 # LC25AF. You are probably thinking, "I said 6 holes, and this one has 8 holes," well that is because the Lippert # LC25AF jack used to have 6 mounting holes, but they updated it to have 8. The change just gives you more options for mounting it securely. It’ll still work fine if your old one had 6...

  • Can I Install the Furrion Chill in My 22 Alpine 3790FK and Control it From My Control Center?
  • Hello Dan, The Command Centers are still pretty new and so is the Furrion chill 18K, so I had to reach out to our friends at Lippert about this one (owner of Furrion, owner of most of the RV world. Fun little game of Monopoly). They informed me that you will NOT be able to link the Furrion Chill Cube RV Air Conditioner w Air Distribution Box Ducted # FR99TD or Ductless # FR59TD to your Command Center. The Furrion chill would still be a great option for adding a 3rd AC because it can...

  • Upgrading Leaf Springs on a 2008 Glendale Titanium Tour Series 5th Wheel Trailer
  • I do have some options for you but I think we need to double check your axle capacity. I looked up the 2008 Glendale Titanium Tour Series 5th Wheel Trailers and the heaviest one I could find (M-36E41TBR) was 12,562 lbs which would be very unlikely to have 8,000 lb axles. The majority of double eye leaf springs max out at 7,000 lbs as well. Therefore, I recommend that you check the axle tube for the identification sticker. If you can send me a photo of this I would then be able to assist...

  • What Hubs and Brakes do I Need for My 2016 Keystone Alpine 5th Wheel with Tandem Axles?
  • Hello James, We definitely have the parts you need, but I do not have a database that supplies me with what is put on what trailer. Life would be a little sweeter if such a list existed. Based on my research the axle capacity on the 2016 Keystone Alpine can vary on what floor plan you have. The 7K axles are the most common, so that is what I am going with (you will want to check your axle tag to confirm that is what they are rated for). For brakes you will want (2) sets of our etrailer...

  • Hey Bill, for a bronze bushing you'd want the part # D014-077-00 and then for a wet bolt part # 126B2. These are sold individually so you'd need to order the quantity of both that you'd need. Should be 8 bushings and 14 bolts.

  • Replacement Brakes for a 2021 Keystone Alpine Fifth Wheel 3910RK
  • Hey, Randall! I did some digging and I keep getting results showing that your camper should have 7,000 lbs Dexter axles. You would want to make sure just in case. If you're unsure you can check the stamp on the hub for a number, all Dexter hubs will have them. I've also gone ahead and linked a help article that goes over other ways to help ID your axle capacity. If you do have 7k axles, you can get part # AKEBRK-7-SA for self adjusting brakes or part # AKEBRK-6 for manual adjusting brakes....

  • Parts Needed to Convert 2018 Keystone Alpine 3701FL to Disc Brakes
  • Hey Jason, since we know your 2018 Keystone Alpine has 7k axles the correct kit you'd need to convert to disc brakes that are oil-bath and not grease is the part # KOD33FR. Then for an electric over hydraulic actuator with brake lines etc you'd want the part # HBA16-252-82.

  • Replacement AC With Heat Pump for 2021 Keystone Alpine 2120RS
  • Hey Kevin! Since you want a unit with a heat pump the Furrion Chill HE Low-Profile RV AC System w/ Heat Pump # FR46AD is the best option. Furrion makes great systems and, their new low profile AC is no exception. This does use a standard wall thermostat so you will have to run wire and find a place to install it. The Furrion Chill Cube is another option, and the best AC out there right now. However, they don't have a heat option yet (we're told a heat strip is on the way but no ETA)....

  • 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!

  • RV Step Recommendation that Can Fit 27 inch Wide Mounting Brackets
  • The closest RV step we offer to 27 inches in width is the Flexco triple step # SMFP-3200L that measures 27-1/8 inches in total width. You might need the outriggers part # LC301704 to move the brackets out to install the steps if yours is 27 inches wide.
