Both the Lund 2010 Pro Guide 2008 and the Lund 2075 Pro-V Tiller 2010 are modified-V designs, both built in aluminium, so the buying decision usually comes down to a handful of practical questions: how many people are you putting on the water, how far do you trailer, and what does your tow vehicle weigh?
On paper these two are close siblings in the size department - Lund 2010 Pro Guide 2008 at 20,0 ft versus Lund 2075 Pro-V Tiller 2010 at 20,7 ft. Weight tells a clearer story for trailering families: the Lund 2075 Pro-V Tiller 2010 tips the scales at 1 890 lbs - 450 lbs less than the Lund 2010 Pro Guide 2008 at 1 440 lbs. That difference is meaningful if you're working within a half-ton or three-quarter-ton truck's tow rating, especially once you factor in a motor, gear, and fuel.
Both boats share a closely matched power ceiling - 115 hp for the Lund 2010 Pro Guide 2008 and 135 hp for the Lund 2075 Pro-V Tiller 2010. Real-world performance will come down more to which motor is actually bolted on, its load at the time, and whether it's a 4-stroke or 2-stroke setup. Fuel capacity breaks the other way: the Lund 2075 Pro-V Tiller 2010 carries 62 gallons versus 40 gallons in the Lund 2010 Pro Guide 2008. On a lake day that's negligible, but for coastal cruising or long reservoir runs the extra range matters.
Both boats are rated for 6 passengers - a good fit for a family of four or five plus guests. Comfort at capacity is another matter; the longer hull typically means more seat options and better weight distribution.
Bottom line: Performance buyers should lean toward the Lund 2075 Pro-V Tiller 2010 and its 135-hp ceiling. If fuel economy and quieter running matter more than top-end speed, the Lund 2010 Pro Guide 2008 with its 115-hp rating is the more economical daily driver.
