I just got a Hobart Hanlder 190 for Christmas, it is an amazing and affordable welder. It does everything I need it to do and then some.
If I want to build a big expedition vehicle box out of mostly 0.065 wall mild steel tube..........,
Don't get me wrong, my intent is not to attack your welding skills. But do you really want to tackle a job that size? Have you considered having someone else weld up the frame. Then use your welder to add items to fit out the shell.
Several years ago a friend and I got the bug to build a pair of Dune Buggies. To save money, he welded his frame, while I purchased mine pre-welded. He did a great job, the welds looked great and appeared strong. It wasn't until he put the wheels and tires on that he noticed a problem. On a level floor one front wheel was about 2" off the ground.
You need to be ever mindful in trying to keep things square as you weld it up. You might need to build a jig to hold pieces square as you tack and weld everything up. This is the skeleton for your total build.

You may even be able to get into an advanced fabrication class and bring you project into the shop as a class project.
If you have the time I would highly recommend taking a course at a local community college.
...I won't be making the mistake your friend made.
I agree though, a class would be nice. I think the internet and you guys will have to do though, because the next classes don't start for 3 months and I am getting started this week and hope to have the frame built by early spring.
If you still plan to tackle the job, a horizontal bandsaw will come in handy along with some clamps.
