Congrats Jim. Great purchase decision.
Don’t rush the PDI. If it takes less than an hour, you’re rushing it. You want to ensure all the important stuff is working before you leave the dealer. And, even some of the small stuff becomes annoying after you’ve left the dealer and found something that doesn’t work, that you may not be able to fix. Overnighting close to dealer is a great idea.
Climb up and inspect the roof during PDI. Big time problems can be intercepted here if you see anything amiss. Get under the trailer and check to see if the coroplast is not buckled and is covering properly. Inspect the tank brace retaining bolts. Look at the brake lines. Inspect the tires for any crazing or bubbles. Check air pressure with the digital tire gauge in your pocket. Make sure that when you hook up, your trailer is level and tv rear squat is less than an inch. It will increase a bit after trailer is loaded.
If you’re good with tools, you should be able to fix most things without having to return to the dealer for warranty service, which can take months. Hunker down, make a list of stuff you can fix and stuff you can’t. Things will fall apart and you’ll find them on the floor. Use blue painters tape and tape the parts to the wall over the kitchen sink. Then when you get home, you can investigate where the part goes, and you won’t lose it by putting it in a drawer.
Your initial tow may not feel great because your trailer will not be loaded with gear and fresh water. So, your tongue weight will probably be too light on the way home. After you get home and have begun to load your camper with gear and fresh water, camp in your driveway for a night to make sure everything is working as expected, including A/C and furnace. Then take your loaded Micro Minnie to a CAT scale and get your weights. First weigh the tow vehicle by itself. Then weigh tv and trailer with no WDH engaged. The difference between tv rear axle weight alone and rear axle weight with trailer hooked up (no WDH bars engaged) will be your trailer tongue weight. After you have these numbers, it becomes very easy to balance your tv loads and trailer loads to get the best tow combination.
