The issues just never end. Unfortunately 17 inch rims are the worst! The highest load tires for that rim size will have a load capacity of 3200 pounds. That pretty much guarantees you will be at or beyond tire load capacity with virtually any 8 foot hard sided camper. I did that for a while. In addition to the safety issue being fully loaded will mean short tire life. You will also have ballooning of the tires which means the sidewalls are likely to be cut on a gravel road. Plan on getting 19.5 rims and tires.
