Ray, you can't use your ham license on CB band. This weekend is amateur radio Field Day. Google it and through ARRL you can find a local club participating in Field Day. Visitors are welcome at these events. Find one near you and visit. If they have a GOTA, Get on the Air station. Unlicensed individuals can get on the air with a licensed Ham.
Older the better for me. Happened more that once had a trailer with a zillion miles and tires over 10 yrs. old. Buy new tires for piece of mind and every other time out Kaa Boom. Like I said more than once. Still running my 20 yr. old (white wall) car tires on one trailer. The tires on my HDT are over 20 yrs. old. Am I in the market for new? No Way To be old and wise had to be dumb and stupid. The one when going out 5 times and having 3 blowouts where Carlisles. They were also over rated for trailer. The others may have been Tow Max.
You sign an affidavit stating that your "Motorhome" has 5 of 7 (6-8??) of the requirements to meet the Motorhome standard. They might ask for pics. We have the fridge, microwave, bed, Portapotty, 120AC power via a separate battery bank. No questions asked.
Our Xantrex killed the batteries on the dealers lot. Dealer didn't maintain the 2 6volt and let them boil dry. Once that issue was resolved, the inverter started working right...... errrr...... Better.
