One of the dash cam names is sainspeed F198 HD portable DVR 2.5 TFT LCD screen, there are other names for the same camera, do a search on Amazon. The night vision sucks as does most of them unless you spend a few hundred dollars or more for one.
I bought a dash cam about 6 months ago for $20.00, bought a 16 gig card (good for 240 hours recording) for $10.00 both from amazon, I showed it to some of my friends and they each bought one. I have 2 motor homes & 2 cars with them in, they loop the video, they turn on and off with the switch,they have a great picture, I carry a extra card in my wallet so that if the police need to see the video for any reason, I can still use the camera with the spare card.I will post the name as soon as I get to my motor home to get one of the boxes.
The one dieharder recommended is as good as any. When you learn how to use the menu in it, it will do anything the more expensive ones will. I sell dash & spy cameras and this is the one that I use for myself. You can get one on ebay for 18.00 with shipping. Use a class 10 sd card in it. Any questions on how to do the menu pm me.
I did a 88 Pace arrow a few years ago. I took the whole side off, the windows, doors & fiberglass. Replaced the rotted wood with 1/4 inch plywood. It took me about a month to do it. I had to cut the fiberglass in half about half way back it was to heavy in one piece. I used laminate glue and drywall screws on the plywood & fiberglass, I had to use a few screws in the fiberglass. The framework was rusted, I used a gas tank coating on it. I did the roof with eternabond tape. Use a lot of the glue it soaks into the plywood, I had a few places that came loose after the sun worked on it.
I changed both of my Motor Homes over to the corn row type, they were 4 to a row, 4 or 5 rows, bright white. They are a lot brighter than the ones that I changed. Bought on EBay $1.50 or $2.00 each. I am changing all of the lights in my house over to LEDs also.
