I guess I would have to say I love my Trap Guide model and it will do exactly what you asked for and alot more. I can pull mine behind the ATV or Snowmobile and all I did was add a set of old snow skis under it.
I have seen alot of home made contraptions out there and pound for pound and all the efforts put in them I think it would ultimately be cheeper to spend the $300 or so and have the sled as well as a pop up shelter.
I could certainly build it better myself but then it would weigh twice as much and be more then I can handle by myself. The trap is easy to load and unload from the truck and fits all my gear, sets up in a minute and pulls twice as easy with the skis on the bottom. This is my third season with it and many more are still forseeable.
I will deffinately replace it with another just like it if ever I have to.
Easily one of the best investments I have ever made for hard water fishing.
