The four incher is a must-buy for vehicles. The clearance on it is just absolutely insane. I've gotten so much mileage already. My sisters vehicles are just stupid tall and this is the best solution I've found for storage and transport. Combine with a couple of iron sheets for maximum effectiveness. Just had to drill four holes in the bottom of the treads for magnets and now they won't move unless I want em to.

Easy to build, looks great, awesome case.

Since I couldn't find a way to edit my below review, I wanted to provide an updated one. After my incident with breaking a large number of the tabs due to my own brute force assembly attempts, customer service got in touch with me. Even though the breakages were entirely my fault, they worked with me to get replacements at either their expense or at cost! It says so much about a company that they are willing to offer a zero-profit solution when their customer was at fault! You should still build slow and follow their instructions carefully - and watch the youtube videos! - but this company is a real gem when it comes to customer service. Now if only they had a double-wide Humpback + for my 8k points of Sigmarines. . . .

If your reading these reviews you already know you want this so do yourself, and your collection, a favor. Save up your spare charge for a minute and pull the trigger! You won't be sorry. The first thing I did when I received my Humpback bundle was order more crystal fortress 😜 and on a side note, the layout layers are possibly the most OCD friendly thing I've ever seen 😀
