How about LED strip lighting? I have found 15 meter rolls fo the stuff on ebay and have had great success with it. You can cut it to desired lengths. I have attached several feet of it inside my RTT fixed to the poles with zip ties. 2 long ones for bright lights, and 2 really short ones over the doors for " I really gotta get out of this tent to use the restroom". I had so much of it left over, I used it on the underneath side of my rack in the trailer and now I have trailer lighting under the RTT when I need to dig something out in the dark. I think I paid $40 for the roll with shipping. I am definately an amature electrician but I was able to get them up and running. The nice thing was, I got the soft white and it really is nice compared to the bright white we see in most LEDS.
