Great work, Sepp. Looking forward to a report on fuel economy.

Were you keeping detailed records before the mods?

i don't have a scangauge or anything, but when i had my rooflights i never was able to reach 700 km with one 65-70 liter tank. wich meanth i was doing 9.2 to 10 l/100 km.

after removing the rooflights i was able to reach 800 km per tank (theoretically, as i had to refill each time before the tank was nearly empty) but the amount left given by the gauge told me i could have reached 800 km.
wich meanth between 8.12 and 8.75 l/100 .

now i have only done about 150 km since i have the cap on, but by the eye i can see a difference on the gauge. as it is split in 4 quarters i always do 200km per line. and now even though only 150 of the 200 km of the third quarter was done with the cap on, i did 220 km before reaching the line. wich can give a vague estimation that now i could be around 7 to 7.5 l/100km! that would be great! lets hope reality is not to far away from that!

btw the EPA for that vehicle is 10.7 l/100 km, so i would be 33% under

ps, most of the miles i do are of the worst kind, several times a day i drive between our two farms, wich are separated by only 2 km, so the engine never gets hot. and when i take the highway (wich is at 500 m of where i live) to go get my GF, it goes up verry steeply for about 2 km, and the engine temp needle usually only starts moving up once im 2/3 rd up the hill.
and to make it worse, my dad drives it aswell and he aint no hypermiler at all

Well, at least there is hope for the rest of the world if the Hummer folks have one.

Hi Sepp;
Great job! I just found this thread - wish I'd had a chance to give you some tips on handling the fiberglass. It really can be a lot easier. I'd have unrolled full-width cloth across the wood, and for polyester, really heated up the wood. Then, I'd pour a puddle of resin on the middle, and quickly squeegee it out to the edges. By using unwaxed resin, you get a tacky surface that will bond well to a coat of Gel-Coat over that. The final coat has wax mixed in to keep air off the surface and allow a full cure.
The Gel-Coat is easy to sand, polish, and patch as you go for a perfect finish. If you can't arrange to spray it on, a coat with a notched trowel, followed by a coat with a regular trowel might work a lot better than brushing it on.
Epoxy is excellent for waterproofing to eliminate swelling, provided it is a continuous coating. I often keep leftover, mixed epoxy in the freezer to use for touchups - if it is properly mixed, you just have to heat it up and wait for hardening. It does not have a sudden transition like polyester.
For truck caps in general, I keep hoping to see a side-hinged unit made of lightweight Coroplast.
