I have finally installed me some solar on my camper. I saved my pennies and got me a 50 watt panel and paired it with a Sunsaver 6. I tried an el-cheapo controller that lasted a whole day before it burned up. For the very little power I use, I think it will be just right. I also changed all my 12volt lights to LED to help with battery consumption. Just thought id thank the folks on here that unknowingly helped in the whole process.
