We have a 19' standard layout with a 2006 Tacoma Double Cab 6' bed. We towed for 9 years with a 1996 Tacoma extra cab, but this year the boys (11 and almost 10 years old) finally outgrew it and we had to get a larger truck. I went with the long bed so we can still nest 4 bikes between the cab and the trailer and still have clearance for turning. We chose the Standard layout so that it is more open inside. We also removed the front couch a couple of years ago and installed temporary storage drawers for extra storage on long trips (we did a 5 week road trip and this worked great).
For the hitch, I bought a used Reese 16K fifth wheel hitch and rails. We removed the rocker arm and installed a thick plate with a 2" ball to the top of the hitch frame and added loops for the safety chains. I then had a local fabrication shop make custom brackets, install them on the frame and install the rails in the bed. We keep the hitch out of the bed unless we are towing (my old Tacoma had the original
Scamp hitch mounted in the bed all the time).
Either way, you'll have a ton of fun and great memories. Buying our
Scamp was the best investment we've made in our family for memories. We do a ton of camping as a family and one-on-one special camping weekends with our kids. One tip that we wish we had done is to keep a log in the trailer where we recorded each camping trip that we did and the highlights of the trip.
