Truck Camper hope to be Newby looking for advice

Moving from a 5th wheel to a truck camper was the same for me as buying my first 5er. I felt the dealer had more experience than I did so I drove the truck in and the next day I drove it out... There are a lot of opinions on what is best.. The dealer installed Happijac tie down system and it has given me good service with no problems for years.. Others may chime in with other suggestions but do your research and I am sure you will make a decision you are happy with...
