Another consideration is will you wish to add a lumber rack.
Around 98/2000 I had a Chevy LUV with an old aluminum topper and lived in an almost pristine wilderness area 15 minutes from the TN state capitol building downtown Nashville, in an old fallin down shack for little of nothin, but part of the deal with the landowner was I would fix it up along the way.
I worked on large construction projects as a carpenter, one was a third floor addition and total remodel of a Dillard's there, when I got in on it they had 6 or 8 large dumpsters out back, and could not get the company to haul them away fast enough. We were working a straight 7 days a week, 10 hour days except on Sunday we'd work a "short" 8 hour day.
Haha just remembered this, WSM AM radio there had a bluegrass music segment every morning @ 5:45AM to 6AM, we started at 6 and I'd pull into the parking area with good ol bluegrass music blarin away
I went by an Ace Hardware after work one day and picked up some 1/8 x 1" angles and some corners and stuff, went home and built a rack onto the topper, drilled and bolted straight onto the frame.
Over the next 6 months or so I filled up the old barn at home with plywood, carpet, trim, etc etc, hek they even gave me about a dozen large unopened bundles of insulation, a load of 2x10s and 2x12s that could have flipped the thing if I had tried to corner too fast.
When that one job was over, I got a lay off and started working about 70 hours a week on the house. I lived there about 7 years and even though it was still an old shack it looked pretty decent and was definitely Not falling down.
Around 2003 I bought an old ragged out 73 Chevy fleetside and put a nice looking LEER on it for $200.
Somewhere in there I tried to find a way to add a rack to it, but it just didn't have the framework the Aluminum had
