Expert Answers about GMC RV Leveling Blocks


  • How Much Weight Can Each SnapPad StakPad Leveling Blocks For RVs And Trailers Hold?
  • Hey Glen, great question, and you’re not alone! A lot of seasoned RVers like you are ready to stop hauling around makeshift wooden blocks to level out the RV. The SnapPad StakPad blocks # SN64VR (white) and # SN74VR (black) are rated for up to 40,000 lbs per pad when used on level, solid ground—plenty of muscle for your Bounder and then some. They’re molded from dense recycled rubber that won’t chip, split, or swell up like old 2x8s in the rain. We’ve had neighbors using these on Class...

  • Availability Of Electric Screw Type Jack That Travels To 48"-50"
  • Hello John, thanks for reaching out. The Ultra-Fab Deluxe Electric Landing Gear Set # UF17-943010 you were looking at is 36" tall retracted and it has 38" or total travel. So this can extend to between 48" and 50" if that is what you are looking for. If you are looking for something with 48"-50" of total travel, I am afraid we do not have anything that large. The # UF17-943010 with 38" of travel is the most available for an electric jack. If you need the jack to cover more space, think...

  • Does Weigh Safe Flap Jack Have Enough Capacity For 2019 Grand Design Momentum 397TH?
  • Hey there Nate, yes, the Weigh Safe Flap Jack Folding RV Stabilizing Block - 8" Tall - 6K # WS63ER will work great for your 2019 Grand Design Momentum 397TH that you say weighs 20,000lbs. The tongue weight / pin weight according to my sources should be around 3,500-45,00lbs at most. Each block is rated to 6k, and you'll actually have 2 up front sharing that weight, so you'll be fine there. Then the landing gear jacks only help to level and stabilize the RV, and you won't be anywhere close...

  • What Kind of Cost Effective Leveling System can I Put on My 2021 Thor Axis 25.6 with Limited Space?
  • Hello Roger, For your Thor Axis, a really solid and budget-friendly way to get true leveling without jumping into a hydraulic system is to go with manual scissor jacks. Two great options available are the etrailer Scissor Stabilizer Jacks w/ Handle and Drill Adapter - 24" Lift - 30,000 lbs - Qty 4 # e74RV, and the Leveling Scissor Jack Set - 24" Lift - 10,000 lbs - QTY 2 # JSC-24. Both are compact, heavy-duty, and offer up to 24 inches of lift, which is more than enough to raise the front...

  • Can Flap Jack Stabilizing Jack Be Used On Trailer Tongue Jacks, RV Leveling Jacks, And Scissor Jack?
  • Hello Layne, great question. The Weigh Safe Flap Jack Folding RV Stabilizing Block - 8" Tall - 6K # WS63ER will work for all of what you asked about - trailer tongue jacks, leveling jacks, scissor jacks. As long as your jack foot fits in the Flap Jack's surface area of 9-1/2" by 8-3/8", you'll be fine! Also make sure you aren't putting more than 6,000lbs on it. I doubt you'd go over since this is such a high capacity. These are available in quantity of 1 # WS63ER , 2 # WS78ER, and 4 # WS88ER.

  • Can The Camco Trailer Tongue Jack Stand CAM44635 Be Used On Uneven Ground?
  • Hello Stacy. The Camco Trailer Tongue Jack Stand # CAM44635 is really designed to be used only on flat, level ground. If you plan to be parked on an angle, you may want to go with a jack stand with a wider base. The Stromberg Carlson Base Pad Peak for Tongue and Stabilizer Jacks # SC86MR is a good option for this, or the Ultra-Fab Leveling Blocks # UF48-979052 will also work well.

  • Is There Longer Adjustment Leg for MORryde StepAbove to Allow for More Height Range
  • Hey Erik, all of the MORryde StepAbove RV steps use the same adjustable legs part # MR36DR so there isn't a longer version available to give you more adjustability there. Do you know which step you have currently and your threshold height? I can see if there's a better option than what you have now.

  • Recommended Lifting Blocks for a Slopped Driveway
  • Hey Mac! If you're using 2x4's the tallest option I have for you is the Ultra-Fab Leveling Blocks item # UF48-979052 that you were looking at. They're 1-3/8" tall and you're going to be limited to stacking them five high. This will give you just below 7" of lift and will be pretty sturdy compared to the wood you're using. How tall are the boards combined that you are currently using?

  • Recommended Suspension Enhancement for a 2025 Chevrolet Silverado 1500 LT W/ 2" Rear Block
  • Hey Levi, for your 2025 Chevy Silverado 1500 LT I recommend going with the Timbren Suspension Enhancement System # T28MR. These springs require no maintenance, has an easy install with no air lines necessary, and is great for consistent loads, like your trailer. Timbren does also offer a spacer kit # A25723-90AH00 which you can stack two to cover distance of the 2" block in the rear.

  • Hello Tom, Congrats on the new 2025 heartland corterra 3.0 5th wheel, what is your favorite feature?

  • RV Trailer Blocking Tail Lights, Any Ideas?
  • Hey Jason, We do not have any tail lights that install adhesively for this type of application. What you could do is use out part # C53201, which are tail lights usually for a bike rack that blocks a vehicles tail lights. This is going to have an adhesive installation like you are wanting, with the lights being 7" long. You would plug into the included 4 flat harness and then depending on how you are planning to install these you could just cut and splice into the wiring. It may...

  • My Tow Bar is More That 3" Out Of Level - Could This Cause The Arms To Not Lock>
  • Hello Phil. So, yes, the tow bar being out of level can definitely cause the arms to not lock, among other problems. Anything greater than 3" out of level is not recommended for this reason. Fortunately, it sounds like nothing on your etrailer SD Tow Bar # e47ZR was damaged, so once you get your adapter you should be good to go.
