Blessed1 Posted January 27, 2014 Has anyone looked into this option? I really need more than the 28 Gallons it comes with from factory. Any auxiliary tank options? I could not find any pics of the under-body & so I will check it out for myself on how much room is down there for more fuel carrying capacities. Thanks for your assistance.

JimmyM Posted February 3, 2014 based on the MPG figures I've seen around here ~15-18 MPG highway, that's a range of 420-504. That will also drop when towing. Quote Share this post Link to post Share on other sites
Bikeboy80 Posted February 4, 2014 I would agree, I wish Nissan had put a larger tank in. I'm getting less than 300 miles range on a fill up. 1 Daydreamin520 reacted to this Quote Share this post Link to post Share on other sites
JimmyM Posted February 5, 2014 I would agree, I wish Nissan had put a larger tank in. I'm getting less than 300 miles range on a fill up.Maybe that's enough for many people. But an Option for a secondary or larger tank would be great. 50Gal would be great. Maybe in the aftermarket? Quote Share this post Link to post Share on other sites
Bikeboy80 Posted February 5, 2014 I saw one the other day that was mounted in place of the spare tire, though I wouldn't want to be without a spare. Let me see if I can find it. Quote Share this post Link to post Share on other sites

axulsuv Posted February 9, 2014 If my memory is at all any good from the time I've spent under my van .... I would think there is plenty of room opposite the OE tank , aka under the slider in front of the rear wheel .Plumbing it in without affecting the evap system would be my major concern ...Glenn Quote Share this post Link to post Share on other sites
Decades Posted March 10, 2014 I think if I were to put in a second tank, it would be mirroring the OEM one but would have to change the exhaust to side pipes. There is plenty of room on the passenger side if the exhaust is re-routed. Mirroring the OEM location would provide peace of mind for crash protection, too.

Heavy Metal Doctor Posted March 20, 2014 I have been towing a bit heavy -- pulling a 7k pound travel trailer -- and found the MPG's do eat up a full tank of gas pretty fast. It's expected and nothing out of the norm for the RV / Travel trailering world, but still annoying to have to stop for gas so often. I have thought about dropping the spare tire and mounting it to one rear door. Then, get a ready made tank (like used in custom car build / sold by Summit Racing or similar suppliers) that will fit the area and add whatever extra capacity that will get me -- whatever fits. even and extra 12 gallons or so would make a world of difference to me as that would allow me make one full leg of trip between camping stops when are RV'n.The hook up can be done fairly easily - I don't have a specific web link handy, but the suppliers like Titan Fuel Tanks link above can sell you a hook up kit that will pump from an aux tank into a fitting added to the existing filler neck tube of the OEM tank system. Just click on the aux pump when the OEM tank gets down low enough and it will transfer the fuel. No muss, no fuss. 1 Daydreamin520 reacted to this Quote Share this post Link to post Share on other sites
ASD Dad Posted April 8, 2015 Doctor - not sure if you are still active here but did you ever mount the second tank? That was a major concern of mine before buying the NVP. My Tundra had a 26 gallon tank and hauling our 6600# camper I averaged 9mpg overall so it ate that up quick. We actually had a close call driving through GA into FL when we were in the middle of Fort Benning and Tates Hell Nat Forrest. No gas station! I almost resorted to dropping the camper on the side of the road and driving off to get gas at one of the tiny small town stations. I havent towed with the NVP yet but I imagine I will get similar mileage if not worse. 1 Daydreamin520 reacted to this Quote Share this post Link to post Share on other sites
Heavy Metal Doctor Posted July 2, 2015 Hey, just checking back up on old stuff here. Reading back over this reminds me of our recent long towing trip. We had 2 times where we ended up in the middle of nowhere and the needle was getting close to E - the warning light finally came on. Both times I had to take an exit, regardless of no "gas here" signs and find whatever I could. Once, I ended up in a tiny shopping center with a gas station at one end in a dead-end parking lot. Fun stuff at 5PM and all the locals getting gas on the way home from work and here I am, the out-of-stater on vacation, trying to squeeze in with 35 feet of camper behind me because I am too low on gas to chance passing the place. On the up-side, my wife thinks I'm a driving god because some onlookers actually cheered me on for not hitting them or the gas pumps with only inches to spare! LOL! On that long trip I had it down to 200 miles between fuel stops -- any over 200 and it was too much risk when in open country. Running out is a PITA, but even more so with a camper in tow. An extra 10 gallons on board sure would be nice! Quote Share this post Link to post Share on other sites
radin2son Posted July 3, 2015 How does a 100 gallon tank capacity sound? A 4x4 NV in AK has this. Can't imagine the cost of filling this, plus it weighs 800+#. Quote Share this post Link to post Share on other sites
caryhecker Posted May 21, 2016 you can easily put a pump tank on the roof or a smaller one on the back door. Quote Share this post Link to post Share on other sites
