    2022 Rossmonster Baja - Chevy 3500 Z71. Fort Collins, CO

    Any suspension work? Skids? Tires appear to be 35s, or close.

    Cut bed of 4 door Tacoma to sleep 6 footer

    Before you get too fancy with a suboptimal situation... think about ditching both the truck bed and cap, and making a composite box that mounts to your frame that a) will be long enough to lay down in, b) tall enough to sit up straight on a seat, c) be well insulated, and d) lighter than what...

    Isuzu npr 4wd

    It would probably make more sense to attach them to your subframe. Mine are ~22" off the ground which is several inches higher than the gas tank and rear tire.

    Check Your Battleborn Positive Terminal!

    After a recent massive share dilution. Their business model of selling generic Chinese products for a premium was bound to fail eventually. Take the money and run. Meanwhile I'm sure the generic Chinese batteries I bought without paying a premium are just fine... :unsure:

    BTU Calculator

    What is the camper you are speaking of, and what are the conditions? Whatever you get, I'd recommend investigating how well it works on low settings, and if it can be easily modded. The 5-8KW Chinese diesel heaters can be turned down to ~2KW and still run efficiently, but no lower. And I've...

    BTU Calculator

    I can tell you that mine with no heat sources inside (like people) and a window cracked, uses about 13 W/degree F. That is the temperature difference between inside and outside. 500 W (x 3.4 = 1700 BTU/hr) would maintain ~38 F temperature difference for instance. I measured this with an electric...

    Is Your Tundra Part of Toyota’s Billion+ Dollar Potential Headache?

    Lexus and international models are made in Japan, or at least they used to be. Or maybe it was just too few to be recall worthy.

    Is Your Tundra Part of Toyota’s Billion+ Dollar Potential Headache?

    I wonder if those overseas engines are identical... or if maybe the tolerances are different...?

    Home Build Composite Panel Flatbed Truck Camper

    If that truck has fully boxed frame rails, you really just need to reinforce the bottom of your camper. I'd honestly just bridge across your current bed mounts with some rectangular hollow beams and call it good. Simple and cheap. If you want to incorporate poly bed mounts for some give, that...

    Alu-Cab ModCAP Hard-sided Popup Build

    I didn't see a photo of how your struts are arranged... did I miss it?

    Alu-Cab ModCAP Hard-sided Popup Build

    I have a full rear hatch style door on my camper. I wanted the struts to fully open it (weighs ~70 lbs) and also pull it closed when it gets close to that point... and not be 500 lb like the calculator suggested! It takes a bit of geometric figuring, but I achieved what I wanted with 150 lb...

    Is Your Tundra Part of Toyota’s Billion+ Dollar Potential Headache?

    Like all of them... well, all are tall, but some are shorter than others. I guess I should be glad my generation of Tundra is short in front of the axle.

    Is Your Tundra Part of Toyota’s Billion+ Dollar Potential Headache?

    I think a lot of this is just the push for more and more power and mpg simultaneously. The engines get overly sophisticated, and they push the envelope for reasonable tolerances. I'd be happy with a simple engine making 250 hp. Shouldn't be too tough to make that reliable and get decent MPG...

    Is Your Tundra Part of Toyota’s Billion+ Dollar Potential Headache?

    There are many such reasons to suspect the debris theory. Newer engines are suffering the same fate, though it's hard to get a good estimate of the numbers. Refining the old 5.7L (or maybe just leaving it alone?) and adding the 10 spd and new frame, would have been a far better move...
