Overlanding options with full access to truck bed?

Are there any options for overlanding in a way that leaves full access to my bed? Like perhaps a tent that is safe to be used on the roof? I would love to be able to bring my dirt bikes with me when I overland but am not sure if this is a viable and/or safe option. Thanks for any help!
I own a ‘21 Tacoma short bed. I’m a pretty small dude, 5 foot 5 on a good day so a 2 person or even a single person tent is more than enough.

 

What about something like this? https://www.discountramps.com/doubl...zKlCXH1mPk7d9LxeLId88DT1yaC8UQv0aAuoiEALw_wcB

 

You could certainly get some of the lighter, smaller RTT's up on top of your cab to keep the bed open. But you won't have much room to mount anything else outside the cab if you're gonna have dirtbikes in the bed. You'll need a pretty light/sparing "overlanding" setup. Unless you got a rear bumper or hitch swingout with a ton of mounting options and space to do so.

Hitch carrier might be a better option like posted above.

 

If you're bringing dirt bikes I think you'll always need to either tow a trailer or do a hitch setup like the comment above. If you want the bikes in the bed, you can always consider an expedition trailer like these https://offgridtrailers.com/expedition-trailer/

 

I run a CVT Mt Shasta on a Sherpa Equiment Company roof rack with no issues

 

I live almost full time in southern Utah. Our valley is an actual inholding in the Grand Staircase/Escalante NM.

I bring this up only because our road bisects trails and roads that access a majority of the monument and over the course of the year I see a lot of overlanders trek into the great unknown.

As someone who spends a lot of time on these trails the last thing I would want is a bunch of weight above the belt line of my truck. In the last week of January we had some wet weather out here. After it passed, the wife and I decided to drive out and do one of our favorite loop hikes. On the way we found a fellow Toyota enthusiast in a 3rd gen tacoma really having a hard time with the degraded and eaten up sections of the trail. He was loaded for bear - rooftop tent, rack, rotopax (it's like 45 miles max to the nearest town) and an additional roof rack full of cases. All that weight up high was really amplifying his side to side moves as he walloped along the trail. We were in our 2019 in which everything is stored in the bed and were able to jet right through it.

We're not talking about rock climbing here amigo, we're talking about a dirt road that most Subarus can handle in the summer after the BLM was done light maintenance on it.

We pulled up ahead of him and I walked back the short distance to where he was floundering. He was a little nervous and worried. I asked him if the bed was full and he said it wasn't. I helped him load as much of the shit he had loaded up high in the bed so that only the RTT remained. Believe it or not it halved the worst of his wallowing,

Most of the time I don't stay out for the night, but when I do, I camp on the ground - or we take the 4R or the FZJ and camp in the back. I am not a fan of how these trucks handle rougher trails with weight up high.
