Dave, I've been using one of these for about 2 years now. Works great, packs up small and doesn't take up a lot of space when transporting. Water pressure is adequate and the water heats up very fast. A 5 gal. water can will shower 2-3 people. I really enjoy mine as do all that camp with me...
As long as this piece of equipment meets your needs its all good. If you need a dedicated grill, as I do, go with the Weber Baby Q (Q 100) Portable Gas Grill by Weber. ABSOLUTLY FANTASTIC AND TRAVEL/ USER FRIENDLY when deep in the bush!
They have been OK for me when I stick to the roads. Not real good in ice but manageable if you keep it slow. However, they are bad in deep snow - not very good at clearing themselves out and quickly perform like a slick.

I have been using the Portable Environment Toilet (PET) system for a few years now and I love it. I highly recomend it. However, if you do buy it and plan to use it outdoors, purchase the Cabella's shower shelter to go with it...
