Upgrade your diesel-powered adventure vehicle with the S&B 40 Gallon Fuel Tank, designed specifically for 2019-2024 Winnebago Revel (4WD chassis), 2022-2023 Entegra Launch, and more. This high-capacity tank replaces the OEM 24-gallon tank, allowing you to extend your travel range and minimize refueling stops.

Features

  • Plug and Play Installation: The S&B tank includes all necessary components for a straightforward installation. It mounts in the stock location using included straps and occupies space forward (11.2 inches) and rearward (5.2 inches) of the original tank, ensuring a seamless fit without modifications.

  • Accurate Fuel Gauge Functionality: Enjoy increased fuel capacity without sacrificing gauge accuracy. The fuel gauge will read full for the first 5-7 gallons before moving normally. Keep in mind that the Distance to Empty will still be calculated based on the stock 24-gallon capacity. For example, with a full 40-gallon tank and 20 MPG, you can expect approximately 800 miles to empty, although your vehicle's gauge may indicate only 480 miles.

  • Built to Last: Constructed from durable ¼” thick crosslink polyethylene, the S&B tank is designed for longevity and reliability. Plus, it’s backed by a lifetime warranty, providing you with peace of mind on all your journeys.

  • Installation Resources: Planning to install your S&B tank yourself? Check out our detailed step-by-step installation video that guides you through the entire process for an effortless upgrade.

Important: The fuel gauge will only work accurately on vans with the J51 fuel gauge (optimized for aux. fuel tap). All 2020+ Revels should have been built with this option but please confirm by sending us your vin or consulting with your installer.
WARNING For Those Using Auxiliary Fuel Tanks

On S&B and OEM diesel fuel tanks, there are one or more rollover valves. The rollover valve uses a float/weight to close the valve when the float is immersed in fuel. This prevents fuel leakage in the event of a rollover. Gravity feed tanks or electronically controlled feed tanks can overfill the S&B or OEM tank. If/when the tank is overfilled, the rollover valves will prematurely close. Without the required vapor space in the tank, this violates the “overfill restriction” requirement of 49 CFR 393.67(12)(i). An overfilled tank can lead to a pressurized fuel tank, leaking, and tank failure. Therefore, the use of a gravity feed tank or electronically controlled transfer tanks (that allow the S&B tank to overfill) in conjunction with a S&B Tank is dangerous and will void the S&B Tank warranty.

My favorite Melatonin supplement
Size: 100 Count (Pack of 1), Style: Melatonin 1mg
I have used this for a few months and really like it. I had previously used a spray that for some reason had added B6 (>2000% RDA) and I developed toxic levels of Vitamin B6 so had to switch. I love that this doesn't have any added garbage including no added flavors, artificial sweeteners or artificial dyes. The taste is fine. It's not candy and isn't supposed to taste like candy. It is just a bland taste that I hardly notice. Dissolves quickly and easily. Love it.

TLDR: Don't wait! Buy it now! This stuff is really great and I think you're gonna love it!
Size: 90 Count (Pack of 1)
Life Extension Neuro-mag: I first learned about magnesium l-threonate on YouTube. It was recommended by several physicians there and in person, all of whom consistently make good suggestions in terms of health optimization. Even still, I didn't go for it right away, unsure if this form of magnesium could really be much different than or better than the liquid magnesium from Life Extension that I've been using with great results for several years now. Still, I was curious, as I did some more research and I kept hearing and reading that magnesium l-threonate is “different” because it crosses the blood-brain barrier. Now I'm not gonna try to explain in detail what that is, but I had an understanding of it enough that hearing this further intrigued me. It's my understanding that the human body has this protective measure in place to protect us and for very good reasons so I wanted to be sure I'm making a safe decision for me. As an overview, basically you want the good stuff you consume, that your brain needs to function, to be able to make it to your brain- but not everything. I don't know how our bodies work this out, but apparently they do, so we don't have to figure it out on our own. Imagine that, trying to tell your gut where to send each calorie and nutrient etc.? Anyway, I decided to give this stuff a chance and within 3 days I knew that I will never go without this form of magnesium again if I can help it. For me, it's really that amazing, and of course as a consumer, I hesitate to say, but it's absolutely worth the asking price and more. I've had years of experience with this brand now too and it's been top notch from the packaging to the product, so I will keep buying from Life Extension. With this I sleep better, problem solving is less stressful and my energy level has improved. It does have the relaxing effect on my body that other forms of magnesium do too, but this one has such a profound effect on my mind it's very difficult to quantify, or put into words in text that can even begin to convey or actually help you comprehend just how powerful the effects are. Kind of like the old saying “you had to be there” I suppose. That said, eventually I did buy the magnesium l-threonate from Life Extension and it is quite literally one of the best decisions I've EVER made in my nearly 50 years. It's weird to say that, am I really that old? Seriously, if you do some research and find that the effects sound like the type you might benefit from- buy it!

Great Product
Size: 90 Count (Pack of 1)
Life Extension’s Neuro-Mag Magnesium L-Threonate is a standout supplement designed to support cognitive health, and after trying it for several months, I can see why it’s so highly regarded. This product contains magnesium L-threonate, a unique form of magnesium that’s specifically formulated to cross the blood-brain barrier, making it highly effective for brain health. Each serving (three vegetarian capsules or one scoop of the tropical punch powder) delivers 2,000 mg of magnesium L-threonate, providing 144 mg of elemental magnesium. Here’s my take on its performance, benefits, and overall experience. Pros: • Cognitive Support: I noticed improved mental clarity and focus after about two weeks of consistent use. Tasks that require working memory, like recalling details or multitasking, felt smoother and less taxing. This aligns with research indicating magnesium L-threonate’s ability to enhance synaptic density and cognitive function, particularly in aging individuals. • Sleep Benefits: While not marketed primarily for sleep, I found that taking it about an hour before bed helped me fall asleep faster and wake up feeling refreshed. This echoes user experiences shared on platforms like X, where some reported better sleep quality and daytime alertness. • High Absorption: Unlike other magnesium forms like oxide or citrate, which are better for whole-body benefits, magnesium L-threonate is designed for brain absorption. Studies cited by Life Extension show it can boost magnesium levels in cerebrospinal fluid by 15% in animal models, which likely contributes to its cognitive effects. • Clean Formula: The capsules are gluten-free, non-GMO, and vegetarian, with no major allergens or unnecessary fillers. The powder version has a pleasant tropical punch flavor, making it easy to mix with water or juice. • Trusted Brand: Life Extension’s rigorous testing for purity and potency gives confidence in the product’s quality. Their transparency, including offering Certificates of Analysis, is reassuring. Cons: • Price Point: Neuro-Mag is pricier than standard magnesium supplements, which might be a drawback for budget-conscious buyers. However, the specialized form and targeted benefits justify the cost for those prioritizing brain health. • Time to Notice Effects: While some users report benefits in as little as six weeks, full effects may take up to 12 weeks, requiring patience. Final Verdict: Life Extension’s Neuro-Mag Magnesium L-Threonate is a high-quality supplement that delivers on its promise of supporting cognitive health. Its ability to enhance memory, focus, and even sleep quality makes it a worthwhile investment for those prioritizing brain function. Great benefits and clean formulation make it a top choice!
