It sounds like you need to try this tried and tested technique
1. Get a box of your preferred
on ice
2. A slave to fetch more
3. allow a week worth of time
4. look through the many build threads and My Camper threads here in Myswag to find what ideas may suit your needs.
The questions you pose just now can't be answered by anyone other than you. I , along with many others here, loitered sniffing around to try to find what suits our needs.
There are a million options out there, and some good quality bargains to be had 2nd hand as well. I'd have 2nd hand Aussie CT over a new import any day, this is due to canvas quality alone.
