if you usually use your vehicle for traveling, you can install truck accessories that can give extra storage. Here's a nice DIY article I found. What This Guy Built Is Brilliant, And Going To Make Truck Owners Very Jealous You can also do this under-the-seat storage
Nicely done; I must say the headline of the story is over the top (i.e., clickbait). The guy made a big drawer. Yay! Yes, it is cool and he did a really nice job. But "brilliant"? Really? He didn't exactly reinvent the wheel. And there are similar commercially made products. I always wanted to do something like this in my truck, except that I need it to haul stuff and can't have it tied up with a mattress, entertainment electronics, and camping gear.
I built a setup just like that only my dividers go length ways for longer storage area for long guns and fishing poles.
When he had a bunch of kids to haul around camping, my Dad made four supported cushions 6 feet long and quarter the width of his pickup bed wide. He made an angle iron frame so they could either be set up as facing bench seats or as a mattress covering the entire width. We also had a folding table for use in the bench configuration.
If I did things all over again I might very well opt for more organization like the setup shown above.
And far from original. The first like it I saw was the one my father-in-law built about 25 years ago for hunting and fishing gear.
Seen a in truck bed pull out drawer tool box like that. It was made out of steel plate.. Was about half box in length And about a 5 gal gas can width from the sides of the bed. He had a fuel transfer tank just behind the cab of the truck.. Nice set up. Heavy enough steel plate so it wouldn't cratter when heavy stuff was thrown on top of it..
Yeah, I think it was cool too. What the truck owner did was quite a long type of drawer. I've also seen some drawer designs with other materials like mesh.
