It's easier than the Sunline. The only hold up is me doing a bit of PEX plumbing to run a valved line to the hot water tank. I'm pretty sure new ones have this done already. We're #006.
We brought the ParkLiner home with my '01 F150, but the trailer towed like a dream, very well balanced and never even a hint of sway. I would suggest all you need is a hitch, a ball mount that is 19" to the top of the ball from level and a 7 pin RV connector, same plug as on Sunlines. Our Sunline did sway, and I had to put a sway bar on for it.
Gail got one of the new turbocharged Escapes with the factory tow package. It's a 2 liter 4 cylinder rated at 231 hp, with a tow capacity of 3500#s (tongue capacity of 350#s). People are already raving about how these little cars tow large rigs. We pretty much bought it to tow a ParkLiner. Unfortunately it only comes with a 4 pole connector, so I need to wire it for 7 pin. The kit to do that cost me 70 bucks, and I figure it'll take me a day to do, maybe less. Last time we were on the highway with it, it got 30mpg, so we're anxious to see how it does with the ParkLiner.
Good luck girls!
