Nice Odyssey. I wasn't too excited to be driving one for a daily driver since I took over minivan duties, but the practicality is growing on me. Interior space is enormous compared to the similar sized SUV. Since I'm driving it, I figure I might as well make the best of it, so I've been slowing modding it to make it more trip friendly. The end goal is to turn it into the ultimate road trip vehicle a la the Wagon Queen Family Truckster (Chevy chase movie reference for the young people). Here are some of the additions I've done,
1. When the kids were young I had added some aux rear view cameras on the interior, so it allowed me to see the infants in the rear seats without having to use a bunch of mirrors. Since they're no longer needed I've been thinking about moving the cameras to under the vehicle to use as "spotter" cameras but really haven't found the need or motivation to do it.
2. Also added some extra 12V power ports under the passenger seat and rewired a few of the aux circuits so the stock cig lighters stay on independent of the key. This way I can leave stuff charging in the car even when it's turned off, and I can keep the 12V freezer powered in the rear circuit on long road trips.
3. Extended the USB port inside the glove box to the ashtray console. Makes connecting a phone or ipod easier for the driver.
4. Put some generic roof rack on so I can mount a RTT or cargo carrier, depending on the trip.
5. I have a couple of small inverters to charge laptops on the road. I'm about to install a 1000W inverter, but I can't find a spot to mount it in the engine compartment.
6. Airlift airbags on the rear to counteract the sagging. Instead of custom springs, you may want to look into these. They stiffen the rear suspension, and as a byproduct it lifts the rear about 3/4" with no load. With load it's probably more than an 1" higher.
I looked into getting some more agressive tires, but honestly with the low ground clearance and horrible approach angles on a minivan, I figure tires are not going to be the limiting factor.
