I think you'll find pavers do not work for a MH pad. The ground will settle under the pavers where you drive it and even more so where it sets and the pavers will soon be kicked up at odd angles all over the place.
Why is it then that many upscale RV resorts use paver pads for their sites? A proper base is necessary for either concrete or pavers. The good thing about pavers is that they can be easily fixed if there is a problem. With concrete, once it is cracked, it stays cracked.
You sure come across as a fear based kind of guy. I really can't believe how much you folks are concerned about theft of RV specific items! Now if you were to camp at Hunts Point in NYC, I'd be concerned. But the vast majority of the places we go in this country, I don't think you should be concerned!
In many cases (mine too) it was not a fear of theft but a desire to be able to check/add air without the nuisance of dealing with add on sensors. If I wasn't purchasing new tires I might have opted for the screw on's but glad I have the internal sensors. Using Alcoa's flow through #001009 double seal valve stem caps makes adding air quick and simple. Simply inflate right through the "cap". The ribbed part (looks threaded) holds the dual foot chuck in place.
Since I was purchasing tires, I opted for the type that has internal sensors. They work great, are invisible and theft proof. Simply mount the sensor onto the rim with a long hose type clamp. Then mount the tire and balance as usual. The sensor and clamp weigh next to nothing so there is no need for extra balancing. I'm sure there are many good systems. The one I choose was Tire SafeGuard. You can mix the internal sensors with screw on for the toad if you wish. They also make an internal stem mounted sensor. If you have an all steel body vehicle such as mine, be sure to get the "N" type monitor as some of the others may not pick up the signals properly.
Is the 20 amp circuit a GFCI protected outlet? Some inverter/chargers "don't like" GFCI circuits. Try shutting off all breakers in the coach then turn on the ones that you need while someone watches for the error message.
