Last year I had the same choice between Chalet Trailer with bike in pickup, or Pop up camper with bike on trailer. Never considered a toy hauler trailer because my pick up is a 4 cylinder Yota.
I went with the Pop Up as pictured below.
Pros:
Fast to set up. Like really fast. Walk around the truck once popping latches, get inside and shove the roof up
If you go somewhere without the dirt bike ( I don't either, but it's nice in theory) No trailer. It can go anywhere your truck can go.
Pretty cheap. Mine is an All Terrain Camper, base price was $9990
Definitely better shelter than a tent trailer, don't know how it compares to the A-Frames
No toilet, I keep a porta-bucket on the trailer if I need it
Not much space to store it
Cons:
No toilet because there's no room for it.
If I don't take the trailer, no real room for firewood or dead deer, and the porta bucket smells like shit if I use it. Not a real problem, since I recently swore off ever going anywhere without the dirt bike.
Don't know if it will clear your roof overhang
Can't get in it to pack stuff unless the bottom is supported, like on the truck
The base model is pretty basic. It includes a stove, sink and ice box, but adding a furnace, battery, jack brackets and cold weather liner bumped mine up to 12.5K. Replacing the Ice box with an actual fridge would also be extra.
Edit: Pro/Con: The manufacture is in Sacramento, so it probably won't be a big drive to pick it up and have them set up your truck. But you will also pay sales tax
. I paid them $300 to deliver it to me, and got to skip out on $900 sales tax in the process
If you have a real truck like my friend there, you can put the bike(s) on a hitch carrier and skip the trailer entirely.
What sold me on the camper versus a trailer, was when my dad and I went hunting last year in the snow with tents, and both said "Having a real shelter here would be awesome, but getting a trailer here would not be"
