I made the siderack from 5/16 roundstock from the hardware store and the Panners came from Wardens Supply an on line army surplus store 39 bucks + shipping about 15 bucks!! The Topbox is a small pelican case I got free I spotted 2 of them in a dumpster outside a paint place. I think they were for gas meters . Wardens supply link http://wardenssupplyco.com/cart/
Mudpuppy The 205 downloaded the tracks just fine . A sd card holds all the info but you need garmin mapsourse to download the files. They want 199 for mapsourse but it can be had for free if you search the net. A ziplock bag works to waterproof it or an unlubed condum works fine but looks goofy . Touchscreen still works with both. Check craigslist you can get a 205w fo 50 bucks.
Martin it was lake superior I had been to erie in June my son rode his TW to Boston and dropped a valve in New York so I got the trailor and went and pccked him up !
My small Garmin doesn't have an SD memory card, but my Nuvi 760 does---I'll have to check out getting Mapsource and the downloads for the T.W.A.T. The baggie I can handle, and maybe RAM or someone makes a mount for it (If not I suppose I could stick it in the clear pouch of my tankbag or something).
When you are actually "off-road" and following the route points you downloaded, what do you see on your screen? Is it a highlighted path similar to how a road looks, or something different? Do you still see streets or other information on things that are nearby (like parks, water, points of interest, etc....) too?
