Much better than the modular 4
Verified Buyer Reviewed by Janet from washington on Saturday, November 1, 2014
The strap that goes around near the top is key. The modular hauler 4 lacks this strap and the entire unit flops around. Also has attachment points for a shoulder strap (that does not come with it) that the Modular 4 is lacking. Yes the extra cube is nice, but having your stuff restrained is nicer... Read More

  • Awesome bag system
    Verified Buyer Reviewed by Molly from Colorado on Sunday, July 29, 2018
    We have two of these!! Great for camping or overnight trips for our family of 5. Highly recommend. You can use one bag to pack for a day trip too. Very convenient to put them all in one big bag for transport.
  • Handy for road trips
    Verified Buyer Reviewed by Sandy from California on Sunday, July 15, 2018
    Love this! I was going to get the 4 cube version but this one fits perfectly behind the back seat of my minivan. Modular design means everyone gets a cube to call their own.
  • As advertised. Love it.

    Looking forward to my next trip - holds an amazing amount of gear.
  • Durable
    Reviewed by TripleDog from Washington on Thursday, May 24, 2018
    I bought some of these 12 years ago and still have them and still use them almost daily. They hold a ton of stuff, are incredibly durable, and easy to use. We use them mostly for groceries, but on trips they are perfect for gear for our dogs, camping supplies, etc. Best thing I ever bought and am tempted to buy them again, though the ones I have now are in perfectly good shape.
  • Organized
    Verified Buyer Reviewed by Camping Friend from Layton, Utah on Friday, May 18, 2018
    Pros: The zippers are quality made and so is the construction.The individual totes help keep things organized and handy. Con: The individual totes need filled to stay rigid. I purchased the Mountainsmith Modular Hauler 4 in the past and have not had any issues. You can also purchase a cooler tote that will fit this organizer. I use the Mountainsmith Modular Hauler 3 in my Subaru Outback so I can easily move it to a desired location to make room for the dog, human, or whatever.

  • “Will if fit under the seat in a commercial airplane?”
    Asked by Stan the Man from South Carolina on 8/30/2016 10:38:36 AM
    • According to the product overview/specs tab: Dimensions: Hauler: 15 x 25 x 15"; Cubes (each): 15 x 15 x7.5"

      Most airlines allowable carry on dimensions are 22”x14”x9” for a total of 45” linear (all together) and weighs 40 lbs. However you may want to check with your air carrier since these may vary some from carrier to carrier

    • Only one case would fit under the seat of a commercial airplane but most definitely not all the cases and tote together. This mod hauler is huge. But one of the colored cases would fit.

  • “I already own these with the vinyl tops. THEY ARE GREAT! Which colors do you get? The site pictures are confusing. Some show red/blue/green no vinyl top; others show orange/gold/blue with vinyl tops. Description states vinyl tops which the red/blue/green DO NOT HAVE. I would prefer the vinyl tops irrespective of color. Thank you.”

  • “Can you use this in a BOB bike trailer?”
    Asked by OnEno from NC on 8/23/2013 12:38:49 PM
    • Looking at the cargo area dimensions of the BOB bike trailers on their web site, it would appear the hauler would fit.
