    Found a Dynamo TCX to finish, looking for input

    I don't think that is a good choice for a camper, as it corrodes readily if it gets scratched. One of the more corrosion resistant alloys would be ok. ACM might be best for this. Or maybe good FRP sheets? Some people have bought from this outfit...

    Does anybody have or have they seen the Vijay bumper systems ?

    There are identical bumpers from other sellers for less.

    What would you do?

    The Tacomas could be had with a 6' bed... is that what you have, or the 5'? Also, the engine on the Tacoma is the 4.0l or the 2.7l? How many miles on the trucks? Is this just you or ...? At any rate I'd keep one of the trucks and build a camper on the frame. That's what I did.

    Would you buy a 2025 Tundra?

    ^I'd use higher viscosity oil. 30-40 on the 2nd number. 1st number depends on what your winters are like.

    Demountable composite box to flatbed mounting system without pivoting subframe.

    Yes, you'd need a better suspension system to compensate... or lockers.

    BTU Calculator

    The thermal conductivity coefficient must be multiplied by surface area and delta T to get the heat (actually power) transferred between inside and out. Volume isn't relevant for conduction, but would come into play if you are figuring so many air changes per hour for infiltration, for instance.

    It's surface area, not volume.

    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...?
