Horst

[gocamp]

For those that did the Horst probes, do you need 3 per tank or 4 probes per tank? Thanks.

Is it fairly easy to change to the Horst probes after one has their trailer? What is involved in changing them? I don't have any of the foam so access is good.

A buddy just drilled new holes next to the old probes and moved the wires over to the new probes. Eliminates risk of reworking the old probe holes.

As long as you DON"T have the sprayed on foam. No idea how you'd get to the enclosed black tank. Both being good reasons to get them installed by ETI during the build.

Actually it's not all that hard (just awkward) to get in under the 21 bed through the outside access hatch. I'm 6 ft and 200 lbs, but it worked. Just set up an outside platform to crawl around on to get in the hole.

I don't have access from under the bed as mine is on a tilted platform with the head 4 inches higher than the foot.

Nothing to add really. Easy to change, if you don't have the spray foam insulation. 4 sensors because there are 4 levels on the monitor. Ours are very accurate - had them installed with the build.
