Economical and easy to fit tracker advice please?

Chris - welcome to CT and good luck with your new MoHo.  I'm afraid, what you are proposing, doesn't exist.  Although I haven't followed through with your link, I'm sure it's going to tell you that only Category 6 or 7 (Thatcham approved) trackers are going to be acceptable to your insurer.  They are not at the 'cheap end of the market' so you will not make any financial saving by fitting one.

If, on the other hand, you want to fit one anyway - just for your own peace of mind - I fitted a Rewire Security tracker to my caravan - costs about £35 for the tracker and the monthly subscription is about £8 - but even if that were acceptable to insurers (which it isn't!), you're only saving a few £s. It's simple to fit and works well - very accurate and sends you an alert if the vehicle is moved etc and has lots of other features. 

The term economical is relative and I have been on a steep learning curve in the last 48 hours.  I was looking for Thatcham approved to get the benefit of premium reduction. So that means S5 or S7. Curiously S7 is lower spec and cheaper than S5!

Assuming the capital cost is acceptable the problem with most products is that the premium saving gets cancelled out by the phone subscription. Surprisingly the best deal I have found so far is  with Vodafone:

This Vodafone S7 system costs £310 including 1 year's subscription and fitting and thereafter £45 p.a. So a saving of circa £65 on next year's premium following this year's outlay. That has some attraction! I might just get it done.

And a bit of good news for me today. The  van MOT'd with no advisories so no obvious  extra expenditure there. Every little helps!

I stand corrected Chris.  Hadn't come across that one before and as you say, if you accept the initial capital expenditure, the annual subscriptions are very attractive compared with most others.
