Well after 5 months of not-so-patiently waiting for winter to end so that we could use our (new to us) TT we finally got in our first trip.
Power, water, stove, oven, Fan, heat, fridge, levelling - thanks to the expertise learned from this and other sites everything worked perfect! Let me tell you after spending my entire life sleeping on the ground [tents] it was an unbelievable experience!
HERE is the only issue which we had. I hope somebody, prolly a newbie like me, can learn from it: Spring Trees drop casings! We purposefully picked the site with tree coverage to give us shade. Unfortunately whichever kind of deciduous tree it was dropped sap-sticky casings all over the ground, the TT, the TV. They got stuck to our shoes and came into the TT and TV. Also once crushed the casings smelled. Since we were only there for two nights we didn't bother moving but man we spent some time cleaning after wards. We had to wash our runners and scrub all of our shoes with cleaning solution to get the sap off.
So the first trip was very successful - everything worked like it should. As a bonus I golfed the best game of my life that weekend. The way I see it the casings weren't a bad thing as we also learned an invaluable lesson about spring camping!
Why did we spend so long sleeping on the ground????
