Hi,
I'm from Australia, and there are very few Truck Campers down here.
These guys have been very helpful. Welcome. Looking forward to your posts.
Now in to my third Truck Camper in 10 years.
First one was a Pine Mountain Popup, then hardsides, Adventurer 910fbs, and now Eagle Cap 1160.
Truck size is rellevant to Camper size. better to have slightly bigger truck than you need.
Go Diesel for Toque, Power & Economy.

Good Luck. Doug
