WOW, I never would've thought the Lexus would have such high numbers. That's 1/2 ton truck payload territory, if I was a betting man I would've lost money. I assume the Lexus has no trailer frontal area limitations? The vehicle and hitch are OK with a WDH?
The weak point is the max tongue weight of 600lbs. The camper will have around that number once it is properly loaded. Then the WDH will add another ~100lbs to the tongue weight. Is that the hitch capacity? Is the rating higher when using weight distribution? Might have to look at an aftermarket vehicle hitch with a higher TW rating if available. Other than that the numbers look good.
Yeah, very under the radar SUV. Shares 90% mechanical w/ the 4runner. 4.7 V8, full time 4wd with 4Lo and Locking Center Diff. Downhill Assist, you can turn off the roll over airbags when getting crazy on steep stuff, 2nd gear start for slippery roads, and very good "simulated" front/rear LSD.
Best part is they are usually owned by mall crawling rich moms who take them in to Lexus for every single service exactly when they are supposed to. Lexus quality is second to none, that is why I laugh when someone suggests a GM or Ford product. They don't hold a candle to Lexus for quality of materials and fit-n-finish, reliability, or longevity.
Regarding frontal area, no idea. The 4.7 V8 has a great rep and plenty of power. The 600lb hitch is from Lexus and there is nothing else out there that increases the capacity. WDH should be a non-issue, it's a body on frame SUV. Strong like bull.
