New Rpod owner- Stabilizing jack question

I am new to the camper world coming from an adventure tent based trailer. I just purchased a 2010 r-pod 151. It has only been used a half dozen times or so and was kept covered and looks to be in great shape. The guy had everything for it but did not have stabilizer jacks. My question is do I need them? Could it damage the trailer if I don't use them? It's only 16 feet long and its just myself and my dog int he trailer. If the answer is yes could you link to some you would recommend? Also the bearings were greased last year according to the guy and the trailer has been sitting for most of that time only being used once. Should I have them greased just in case? Thanks in advance....

We also have a 151 that we purchased used a few years ago.  In my research, it seems that the 151 and 152 did not come with front stabilizer jacks.  These early production  models only had the stabilizers on the rear.  I purchased a set of jacks on Amazon,  drilled a couple of pilot holes and they were easy to install. I just checked my Amazon history, and it was a pair of 20" scissor jacks that I purchased.   I do believe you need them as our trailer was quite wobbly with out them.

Thanks for the input..I ordered 2 for the rear and see how that goes...I don't feel confident about drilling into metal but Im guessing there might be pre drilled holes since it was supposed to come with them from the factory...I was advised on my old 18 gallon fresh water tank in adventure trailer to not drink from the tank....So i bought a couple fo 5 gallon jugs...Do most people drink from the faucets or take their own drinking water? If I dont drink from it do i still need to treat and clean the tanks?

We bring a couple of jugs of water filtered through our refrigerator filter system. Even though we do not drink water from the tank, I still do the Clorox - vinegar routine every spring when I do de-winterization.
