Have you weighed your cargo?

Hi -
Have you weighed all the 'stuff' you put into your RV before an extended trip? This would include kitchen gear, food, bedroom linens, first aid stuff, bathroom stuff, clothes and shoes, toys games and activities, nature book, binoculars, photo equip, computers, toolbox, camp chairs, bikes etc, etc, ...??
I'm trying to get a fix on whether my list is in line with normal. Thanks !
