Not at all free modification's but necessary creature comfortable, and
noteworthy,

Nicro Solar powered roof vent.

It most certainly moves hot, stale air out of the Van.

Front window accessory Air Conditioning.

I don't know how I would have survived (especially this extra hot)
summer without it.

The rear window limo tint.

It for sure helps keep some of the suns rays out of the Van, and also
keep's wandering eyes from viewing the Vans content's .

Headlamp relay's, and the Hella bigger wattage headlamp bulbs.

This sure helped me see well at night.
I can't believe how poor the stock headlamps were till I installed this
update.

Bright tail lamps.

This makes me feel good knowing the back end of the Van can be seen
easily by other motorists.

I can't really think of one favorite modification that didn't cost me
something.
