I love the shape of our Puck L ( kitchen at the front). It gave my tall husband a better ability to wash up than the other configuration.
With regards to searching for a suitable Puck I think we paid "top whack" from AL, but because we were total caravan newbies we felt more comfortable than , for us, risking getting it wrong.
We found AL great to deal with.....we went there a lot and were never put under any sales pressure.....another thing we really appreciated. They were always very polite, friendly and helpful.....answering numerous "newbie" questions until we totally narrowed down which model we wanted. Every time we visited to start with we were confused with different models and layouts, but they patiently explained until we MOSTLY understood the differences.
Having completed trip 2 we have a small problem so have emailed them about it and we have had a prompt reply advising us to take the van back in and they will fix it under its warranty.
Happy hunting.....
