We use an 9.5' inflatable bought on e-bay. Store it in the p/u bed or inside the 5er door. Comes in a nice storage bag. See link:
Baltik BoatUnder $1000. Very durable. Been using it for 3 years. Takes an hour to set up (with hand pump and gin&tonic) and an hour to wash down and rebag. Has a keel so it paddles just fine.
Power it with a massive 3.3hp Evinrude. Great for trolling. Pulled in lake record trout (14 lb 12oz) at Lake Morena, CA.
Fish Picture/ArticleAlso use it for deer hunting. Transported two deer across the lake this year from a remote valley.
DW and I love our land yacht(the Montana) AND our embarked boat.
