I am thinking of building a trailer 24" w X 30" long out of 1" PVC pipe with 20" bike front wheels. With homemade hitch attached to the seat post. Does anyone have any ideas how I can test for weight limits? I also found a camping cot/tent for about $125 so I could make a camper would use small C clamps to hold cot/tent to trailer for a ride of 150 miles ( one way ) I am planning for labor day weekend.
